I am developing an application in Flex using the cairngorm module library and Parsley.
Parsley documentation chapter 5 says: "Interceptors may come in handy when you want to decide whether or not the message should be passed to handlers".
When using the ModuleMessageInterceptor the above is not true. Which means that my MessageHandler receive the message before the MessageInterceptor.
Does anyone knows a work around?
Regards,
Fadi
The solution to this problem was extending the ModuleMessageInterceptor class as follows:
package fr.core.patch.cairngorm
{
import com.adobe.cairngorm.module.ModuleIdMetadata;
import com.adobe.cairngorm.module.ModuleMessageDispatcher;
import com.adobe.cairngorm.module.ModuleMessageInterceptor;
import com.adobe.cairngorm.module.ParsleyModuleMessage;
import flash.system.ApplicationDomain;
import org.spicefactory.lib.reflect.ClassInfo;
import org.spicefactory.lib.reflect.Property;
import org.spicefactory.parsley.core.registry.ObjectDefinitionRegistry;
import org.spicefactory.parsley.core.registry.RootObjectDefinition;
import org.spicefactory.parsley.tag.messaging.MessageHandlerDecorator;
import org.spicefactory.parsley.tag.messaging.MessageInterceptorDecorator;
public class ATPModuleMessageInterceptor extends ModuleMessageInterceptor
{
public function ATPModuleMessageInterceptor()
{
super();
}
public var order:int;
private var target:Property;
override public function process(registry:ObjectDefinitionRegistry):void
{
target=getModuleIdTargetProperty(registry.domain);
var interceptor:MessageInterceptorDecorator=new MessageInterceptorDecorator();
interceptor.type=type;
interceptor.selector=selector;
interceptor.method="interceptModuleMessage";
interceptor.order = order;
var messageHandler:MessageHandlerDecorator=new MessageHandlerDecorator();
messageHandler.type=ParsleyModuleMessage;
messageHandler.method="parsleyModuleMessageHandler";
var definition:RootObjectDefinition=registry.builders.forRootDefinition(ModuleMessageDispatcher).decorators([interceptor, messageHandler]).buildAndRegister();
definition.constructorArgs.addValue(target);
if (moduleRef)
{
definition.constructorArgs.addIdReference(moduleRef);
}
}
private function getModuleIdTargetProperty(domain:ApplicationDomain):Property
{
var props:Array=ClassInfo.forClass(type, domain).getProperties();
for each (var prop:Property in props)
{
if (prop.hasMetadata(ModuleIdMetadata))
{
return prop;
}
}
return null;
}
}
}
By doing the above we have added the order property to the ModuleMessageInterceptor which solve the problem I had.

In Parsley 2.4, MessageInterceptors have been depracated:
And ModuleMessageInterceptor is not a Parsley thing, it's a Cairngorm thing. Personally, I'd stay away of Cairngorm altogether because of my experience with it. After looking online, I saw that other people had similar issues. Your best bet is to post on the same forum and hopes somebody helps.

I'm using flutter , and I tried to use Native Ads following this doc
all ads are working fine but Native ad doesn't work and it fails building the app showing this error
error: cannot find symbol FirebaseAdMobPlugin.registerNativeAdFactory(flutterEngine, "moviesTorrentAdFactory", NativeAdFactoryExample());
this is MyActivity.java file :
package tech.devm.movies_torrent;
import io.flutter.embedding.android.FlutterActivity;
import io.flutter.embedding.engine.FlutterEngine;
import io.flutter.plugins.firebaseadmob.FirebaseAdMobPlugin;
import com.google.android.gms.ads.formats.UnifiedNativeAd;
import com.google.android.gms.ads.formats.UnifiedNativeAdView;
import io.flutter.plugins.firebaseadmob.FirebaseAdMobPlugin.NativeAdFactory;
import java.util.Map;
public class MainActivity extends FlutterActivity {
#Override
public void configureFlutterEngine(FlutterEngine flutterEngine) {
flutterEngine.getPlugins().add(new FirebaseAdMobPlugin());
FirebaseAdMobPlugin.registerNativeAdFactory(flutterEngine, "moviesTorrentAdFactory", NativeAdFactoryExample());
}
#Override
public void cleanUpFlutterEngine(FlutterEngine flutterEngine) {
FirebaseAdMobPlugin.unregisterNativeAdFactory(flutterEngine, "moviesTorrentAdFactory");
}
}
class NativeAdFactoryExample implements NativeAdFactory {
#Override
public UnifiedNativeAdView createNativeAd(
UnifiedNativeAd nativeAd, Map<String, Object> customOptions) {
// Create UnifiedNativeAdView
}
}
is there should be any changes to Manifest.xml file ? or am I missing something ?
I've cleared the build using (flutter clean ) many times but nothing works
any help would be much appreciated
I was also having the exact same issue. This is how I fix it!
Seems that this error is related with the NativeAdFactory file (eg: ListTileNativeAdFactory.java) and the layout at app/src/main/res/layout/list_title_native_ad.xml
If you go to the Google Codelabs example at https://github.com/googlecodelabs/admob-inline-ads-in-flutter/tree/main/complete and copy those files exactly like the example you will solve that problem.
I made a project like this sample. So the controllers are like this
package mypackagename.controller;
import org.springframework.web.bind.annotation.RestController;
import org.springframework.web.bind.annotation.RequestMapping;
#RestController
#RequestMapping("/")
public class StoresRestController {
#RequestMapping(method = RequestMethod.GET)
public String stores() {
return ...
}
}
I like to handle all throwables and make my customized unified response. The problem is I cannot find a guide or a sample to do this correctly.
First of all, I tried ExceptionHandler, with Throwable, but it didn't work, so I decided to move on. Then, the most close approach that I found is this, so I tried jersey, by adding something like this. But it's not working for all throwables. Also, it's ignoring my controllers, by complaining
o.g.jersey.internal.inject.Providers : A provider mypackagename.controller.StoresRestController registered in SERVER runtime does not implement any provider interfaces applicable in the SERVER runtime. Due to constraint configuration problems the provider mypackagename.controller.StoresRestController will be ignored.
I searched for this error and found this, which I'm not using ContainerResponseFilter in my project as I provided the sample above. So I'm clueless. The main problem is how to handle all throwables, but if you can give me some suggestions about how to solve Providers problem, I'll be so appreciated.
In my project I use #ControllerAdvice to handle my exceptions. Here's an example. Hope this helps. Just make sure this class is on your component scan so it gets picked up.
#RestController
#ControllerAdvice
public class StoresExceptionHandler {
#ExceptionHandler(Throwable.class)
public ResponseEntity<Object> handleThrowable(final Throwable ex) {
return new ResponseEntity<Object>("Unable to process request.", HttpStatus.INTERNAL_SERVER_ERROR);
}
}
Finally this post helped me to handle all Throwables, except authentication exceptions. The important part was to use #EnableWebMvc and ResponseEntityExceptionHandler. To handle authentication exceptions I used this answer. Hope it's helping someone.
as #carlos-cook said, you could use a #ControllerAdvice and, ProblemDetail defined in RFC 7807 which could look like:
import org.springframework.http.ProblemDetail;
import org.springframework.web.bind.annotation.ControllerAdvice;
import org.springframework.web.bind.annotation.ExceptionHandler;
import org.springframework.web.context.request.WebRequest;
import org.springframework.web.servlet.mvc.method.annotation.ResponseEntityExceptionHandler;
#ControllerAdvice
public class GlobalExceptionHandler extends ResponseEntityExceptionHandler {
#ExceptionHandler(RuntimeException.class)
public ProblemDetail handleUnexpectedException(RuntimeException rte, WebRequest wr) {
ProblemDetail pd = this.createProblemDetail(HttpStatus.INTERNAL_SERVER_ERROR, rte);
pd.setType(URI.create("http://your-site.com/internal-server-error"));
pd.setTitle("Internal server error");
return pd;
}
#ExceptionHandler(YourCustomeException.class)
public ProblemDetail handleUnexpectedException(YourCustomException rte, WebRequest wr) {
ProblemDetail pd = this.createProblemDetail(HttpStatus.INTERNAL_SERVER_ERROR, rte);
pd.setType(URI.create("http://your-site.com/custom-error-page"));
pd.setTitle("Internal server error");
return pd;
}
}
Then in your controller you could simply throw YourCustomException
This controller advice will handle every exception and YourCustomException separately.
I'm making a mod, and I am getting an error(no duh) and I have tried searching it up but I want an answer specific to my problem because I am not very good at this. I am getting this error in my block class.
Implicit super constructor Block() is undefined for default constructor. Must define an explicit constructor
and I don't know how to fix it. Please Help its for a project.
block class:
package GDMCrocknrollkid.fandomcraft;
import net.minecraft.block.Block;
import net.minecraft.block.material.Material;
public class BlockCbBlock extends Block {
protected BlockCbBlock(Material material) {
super(material);
}
}
mod class:
package GDMCrocknrollkid.fandomcraft;
import net.minecraft.block.Block;
import net.minecraft.item.Item;
import cpw.mods.fml.common.Mod;
import cpw.mods.fml.common.Mod.EventHandler;
import cpw.mods.fml.common.event.FMLInitializationEvent;
import cpw.mods.fml.common.event.FMLPostInitializationEvent;
import cpw.mods.fml.common.event.FMLPreInitializationEvent;
import cpw.mods.fml.common.registry.GameRegistry;
#Mod(modid = "fc", name = "Fandomcraft", version = "1.0")
public class fandomcraft {
public static Item itemCbIngot;
public static Block blockCbBlock;
#EventHandler
public void preInit(FMLPreInitializationEvent event){
//Item/Block initialization and registering
//Config Handling
itemCbIngot = new ItemCbIngot().setUnlocalizedName("ItemCbIngot").setTextureName("fc:itemCbIngot"); //item.itemCbIngot.name
blockCbBlock = new BlockCbBlock(Material.iron);
GameRegistry.registerItem(itemCbIngot, itemCbIngot.getUnlocalizedName().substring(5));
}
#EventHandler
public void init(FMLInitializationEvent event){
//Proxy, TileEntity, entity, GUI and Packet Registering
}
#EventHandler
public void postInit(FMLPostInitializationEvent event) {
}
}
This error pertains to all of java, not just minecraft forge. Check this for some more reference. There are a couple possible reasons for this error. It is most likely 1, but 2 and 3 can be a contributing factor to the error.
Your BlockCbBlock Class declares a constructor that is not the default, no-argument constructor that the compiler would otherwise provide (that is, if the Block class doesn't have a constructor) and, if in fact the Block class is using the default constructor, then you can't call super() on the arguements because the Block class uses a constructor with no arguments. Because of this, if you wanted to modify the Block constructor, it would be safier and easier to create a custom construcotr inside of the BlockCbBlock class itself.
You are trying to inherit the constructor of Block, but you have declared it as protected, when the constructor in your class should be public to match the inherited .
If you're using Eclipse, it can give this error when you have your project setup incorrectly (system configuration mismatch)
Probably not directly realted to this specific error, but a possible cause of other errors in the near future; you are using the annotation #EventHandler, but you have not actually declared the forge event handler.
You don't actually register the block for some reason. Even if you're using the block as a recipe item, you still need to register it
To fix potential problems 1, 2, and 4, try this (obtained from here):
package GDMCrocknrollkid.fandomcraft;
import net.minecraft.block.Block;
import net.minecraft.block.material.Material;
private final String name = "BlockCbBlock";
public class BlockCbBlock extends Block {
public BlockCbBlock() {
super(Material.iron);
GameRegistry.registerBlock(this, name);
setUnlocalizedName(Reference.MODID + "_" + name);
setCreativeTab(CreativeTabs.tabBlock);
}
public String getName() {
return name;
}
}
This way, you'll declare its UnlocalizedName, Material, and CreativeTab ahead of time. This method might be unnecessary, but its a good precaution to help prevent the error. Now, all you have to do is declare it like this:
//You need to make your own EventHandler class. Search online for that.
FCEventHandler handler = new FCEventHandler();
#EventHandler
public void preInit(FMLPreInitializationEvent event){
//Config Handling
//event handler registry
FMLCommonHandler.instance().bus().register(handler);
MinecraftForge.EVENT_BUS.register(handler);
//the same thing can be similarly done with this if you wish
itemCbIngot = new ItemCbIngot().setUnlocalizedName("ItemCbIngot").setTextureName("fc:itemCbIngot");
blockCbBlock = new BlockCbBlock();
GameRegistry.registerItem(itemCbIngot, itemCbIngot.getUnlocalizedName().substring(5));
}
Ok this probably sounds dumb but Im a complete beginner in Flex programming.
I have an application with a main .mxml file, and a certain class Foo that I call from the .mxml
In Foo, I make a URLRequest and listen for the Complete event. Then I found myself with the returned data in a Foo function, but I have no idea how to communicate it to the .mxml part of the applicaton ! I looked into ArrayCollections but I can't seem to understand how they work and whether it might help. Isn't there a way to modify, from inside the class, a variable with a global scope ?
This sounds like a small application, but if it's a large application you might want to look at a micro-framework like RobotLegs
If you have your Foo class extend EventDispatcher then it will be able to send events and have the main MXML app listen for said events.
package com.example
{
import flash.events.EventDispatcher;
import com.example.events.MyEvent;
public class Foo extends EventDispatcher
{
public function doAction():void
{
var someData:String = "blah";
dispatchEvent(new MyEvent(MyEvent.SOMETHING_HAPPENED, someData));
}
}
}
A Custom event with a payload (in this case a string)
package com.example.events
{
import flash.events.Event;
public class MyEvent extends Event
{
static public const SOMETHING_HAPPENED:String = "somethingHappened";
private var _myData:String;
public function get myData():String
{
return _myData;
}
public function MyEvent(type:String, myData:String, bubbles:Boolean=false, cancelable:Boolean=false)
{
_myData = myData;
super(type, bubbles, cancelable);
}
override public function clone():Event
{
return new MyEvent(type, myData, bubbles, cancelable);
}
}
}
Working with your Foo class from the main file:
public function EventDispatcherExample() {
var foo:Foo = new Foo();
foo.addEventListener(MyEvent.SOMETHING_HAPPENED, actionHandler);
foo.doAction();
}
private function actionHandler(e:MyEvent):void {
trace("my data is: " + e.myData);
}
import mx.core.FlexGlobals;
FlexGlobals.toplevelApplication.varName;
Your Foo class can dispatch an event and have something in you main.mxml listen for that event. I am sure that I could create an example. I think it is under customer events in Flex documentation. This is assuming I understand the question.
As John said, an event is your best choice.
If you'd like some example code, I provided some for a similar question here: Data from Popup to Main Application?
An event might be the best way to do it as it has been stated.
Another approach is to dispatch an event like this
dispatchEvent(new Event('somethingHappened'));
and also create a get method in your class for the data you need to get.
Then all you have to do in your main app is this
var foo:Foo = new Foo();
foo.addEventListener('somethingHappened', actionHandler);
private function actionHandler(e:Event):void
{
trace(foo.memberData);
}
This way might be more suitable if the data should be a class member anyway and if you would like to avoid creating a new event class.
ActionScript 3 / Flex 3 - Adding custom events to a class
Say I have the following Event:
import flash.events.Event;
public class SomeEvent extends Event
{
public static const EVENT_ACTION:String = "eventAction";
public function SomeEvent(type:String) {
super(type);
}
override public function clone():Event {
return new SomeEvent(this.type);
}
}
... and the following Class:
public class SomeClass extends EventDispatcher
{
public function someFunction():void
{
dispatchEvent(new SomeEvent("eventAction"));
}
}
What is the best way to show that 'SomeClass' throws 'SomeEvent'? The only way I have found is to decorate 'SomeClass' with the [Event] attribute, as follows:
[Event (name="eventAction", type="SomeEvent")]
This allows me to instantiate the class and add an event listener by doing this:
var someClassInstance:SomeClass = new SomeClass();
someClassInstance.addEventListener(SomeEvent.EVENT_ACTION, mycallbackmethod);
Is there a better way to do this? Putting the [Event] attribute on the class followed by some string literals just feels ... wrong. Thanks in advance for the help!
You're doing it right. Currently, the AS3 compiler allows only string literals in metadata. Constants cannot be used.
By the way, Adobe's public bug database has a feature request to allow ActionScript constants in metadata. Feel free to vote for it.
I know, I feel the same way; using the string literals does seem a bit wrong somehow. But to the best of my knowledge, from all the documentation I've seen and the talks I've attended and in reading the Flex source code, etc., it does appear that's the proper way to do it.
