I want to create some sort of global error handling in my Flex application. What is the best approach for this?
Right now there isn't a way to do this. So please go vote for this feature request:
http://bugs.adobe.com/jira/browse/FP-1499
Global error handling is now available in Flash Player 10.1 (released June 2010). For details on how to use it, see
http://help.adobe.com/en_US/FlashPlatform/reference/actionscript/3/flash/events/UncaughtErrorEvents.html
James is right... you could start by routing exceptions to one static util like below to make changes and debugging easier.
package
{
import mx.rpc.Fault;
public class FlexException
{
public function FlexException()
{
}
public static function faultHandler(fault:Fault):void{
//Do stuff
}
}
}

I'm using AssertJ to test web using fluentlenium and extent reports for reporting the results.
I asked before the question but forgot to mention the use of AssertJ.
The provided answer was to extend soft assert and that it has onAssertFailure function.
Is there anything like this for AssertJ soft assertions? Or is there another solution to bypass it?
In the next AssertJ version (2.5.0) you will have access to all soft assertions errors (see this commit).
Hope it helps
In a future release of assertJ a method wasSuccess() is added (as can be seen on git history), but it is not yet available in the current release.
When this method is added you can do something like this:
public class AssertjSoftAssert extends SoftAssertions {
private void checkFailure() {
if(!wasSuccess()) {
onFailure();
}
}
private void onFailure() {
//doFailureStuff
}
#Override
public BigDecimalAssert assertThat(BigDecimal actual) {
BigDecimalAssert assertion = super.assertThat(actual);
checkFailure();
return assertion;
}
#Override
public BooleanAssert assertThat(boolean actual) {
BooleanAssert assertion = super.assertThat(actual);
checkFailure();
return assertion;
}
}
Do note, however, that you will have to override EVERY assertion method in the SoftAssertions class like I've shown you with the examples here. And also if new Assertions are added to the SoftAssertions class you will have to override those as well. This is the best solution I could find right now, but won't work until assertj is updated either.
EDIT: Actually I am not sure this would even work because I am not sure wasSuccess() will return true after every successvul softassert or only after throwing assertAll() but I can't test this obviously as the feature isn't out yet.
Bonus: The commit that added wasSuccess()
I want a variable bound to the application scope, (in java that would be application scope).
I thought service should be the thing to use in order to reach my goal.
I created a service test
<?php
namespace Acme\MyBundle\Service;
class test {
public $count;
public function __construct() {
$this->count = 0;
}
public function addCount() {
$this->count++;
}
}
which I declared in services.yml
acme.my.service.test:
class: Acme\MyBundle\Service\test
I call it in my controller
public function testAction() {
$this->get('acme.my.service.test')->addCount();
return $this->render('AcmeMyBundle:Test:test.html.twig');
}
But when I retrieve it in my twig, the value is 1, no matter how much I refresh or go with multiple session on the url bound to my testAction.
=> It means that constructor is called each time.
So is that the right way to do? I thought services were created once and reused then, but I may be mistaken.
Could you please enlighten me?
Thank you,

I found what I was looking for, APC caching system.
Easy to use and integrated to doctrine common.
How to cache in Symfony 2?

I am trying to dispatch a custom event from one flex module to another.
The code which dispatch the event is as below
Application.application.Destination.child.dispatchEvent(
new AlgoEvent(AlgoEvent.GETFROMPARENT_LOCAL_EVENT));
here AlgoEvent is a custom event
on the other side the module which catches and handles the event has this code:
public function sendParametersToChild(e:AlgoEvent):void
{
//some codes
}
but when the statement Application.application.Destination.child.dispatchEvent(new AlgoEvent(AlgoEvent.GETFROMPARENT_LOCAL_EVENT)); is executed the debugger give the following run time exception:
TypeError: Error #1034: Type Coercion failed: cannot convert resources.events::AlgoEvent#4182239 to resources.events.AlgoEvent.
at flash.events::EventDispatcher/dispatchEventFunction()
at flash.events::EventDispatcher/dispatchEvent()
at mx.core::UIComponent/dispatchEvent()[C:\autobuild\3.2.0\frameworks\projects\framework\src\mx\core\UIComponent.as:9298]
at components::Destination/sendTimeToChild()[E:\FlexProjects\MyApp\src\components\Destination.mxml:99]
at components::Destination/updateParameters()[E:\FlexProjects\MyApp\src\components\Destination.mxml:206]
at components::Destination/__CreateBasketButton_click()[E:\FlexProjects\MyApp\src\components\Destination.mxml:558]
I am not able to identify what is going wrong here.
Please help to solve this problem
This is my Event class
public class AlgoEvent extends Event
{
public static const GETFROMPARENT_LOCAL_EVENT:String = "getfromparent_local";
private var eventType:String;
public function AlgoEvent(eventType:String, bubbles:Boolean=false, cancelable:Boolean=false)
{
super(eventType,bubbles,cancelable);
this.eventType=eventType;
}
}
While debugging am getting error in this funcion of UIComponent class
override public function dispatchEvent(event:Event):Boolean
{
if (dispatchEventHook != null)
dispatchEventHook(event, this);
return super.dispatchEvent(event);
}
Excaxtly this line gives the error: dispatchEventHook(event, this);
Import the AlgoEvent class in the main application and create a reference to it.
import resources.events.AlgoEvent;
private var dummyEvent: AlgoEvent;
Some explanations for this could be found here: Module domains
If your custom event doesn't carry any special event properties you could workaround your problem by using the standard Event class.
dispatchEvent(new Event(AlgoEvent.GETFROMPARENT_LOCAL_EVENT));
I had the same problem when dispatching, solved overriding two functions:
override public function clone():Event
{
return new AlgoEvent(type, bubbles, cancelable);
}
override public function toString():String
{
return formatToString("AlgoEvent","type"","bubbles","cancelable","eventPhase");
}
hope it helps out :)
Mr. splash suggested a solution which worked fro me:
Try to make the Custum Event (Algo Event in my case) class known to the main application.
I.e import it in the main application and create a variable of it..
And it works for a main reason>>when we try to communicate betwwen the modules using event dispatching what happens is :the modules are loaded at the run time but the classes like event classes are linked to the modules at the run time..
But the Event class is compiled before the modules are loaded..
application defines a Custum Event Class at compile time, and the module defines its own Custum Event Class when it is published. Then when the application is run, the Custum Event Class dispatched in the application doesn't match the one in the module
swf.
For the problem which is causing this error one can check the link:
http://www.kirupa.com/forum/showthread.php?t=320390
and also

Mate framework takes care of all this.
It gives you a global event bus, for all modules in your app.
http://mate.asfusion.com/
Try to override the clone() method in your customized Event,AlgoEvent.
Add the following code to your AlgoEvent.as class and try:
override public function clone():Event{
return new AlgoEvent(eventType,bubbles,cancelable);
}
HTH.
Your custom Event class should look like this:
public class AlgoEvent extends Event
{
public static const GETFROMPARENT_LOCAL_EVENT:String = "getfromparent_local";
public function AlgoEvent(type:String, bubbles:Boolean=false, cancelable:Boolean=false)
{
super(type, bubbles, cancelable);
};
override public function clone():AlgoEvent
{
return new AlgoEvent(type, bubbles, cancelable);
};
};
You should use the Event's inherited type property instead of creating a new one.
Also, the UIComponent has it's own dispatchEvent method, so you don't have to create your own - only if it works differently to the inherited one.

Okay, it must be said that what you're doing, from an architectural standpoint, is wrong. Calling Application.application is bad for so many reason, especially if you're then starting to go down the display tree. The second any of the children changes, your build is now broke, and you won't know that until runtime because it's a module.
What you need is an application framework. A way to increase complexity without decreasing maintainability. There are many out there, but my personal favorite is Parsley. I've used it on many very large projects with much success. The problem you're trying to solve right now, dispatching one event where the other module listens for it, is extremely trivial (can be done in about 3 lines of code).
I recommend you look it over as well as my presentation on an introduction to parsley.
Based on this article, I've written a custom class which implements the Watin.Core.interfaces.IFindByDefaultFactory, but I don't think I'm correctly assigning it to the watin settings, because it is never used.
Basically, Where/when should I assign to the Settings.FindByDefaultFactory? I've tried in my test Setup, and the text fixture's constructor, but neither seem to cause my custom class to be used. The tests still run and work, but I have to use the full asp.net ID's.
I'm using Watin 2.0.15.928 in VS2008 from nUnit 2.5.2.9222. I am running visual studio as administrator, and tests run sucessfully as long as I don't rely on my custom find logic.
Here's what the start of my text fixture looks like, where I set the FindByDefaultFactory
namespace Fundsmith.Web.Main.BrowserTests
{
[TestFixture]
class WatinHomepageTests
{
private IE _ie;
[SetUp]
public void Setup()
{
Settings.FindByDefaultFactory = new FindByAspIdFactory();
_ie = new IE("http://localhost/somepage.aspx");
}
//etc etc...
And this is what my custom Find By Default factory looks like (simplified), unfortunately, it's never called.
using System.Text.RegularExpressions;
using WatiN.Core;
using WatiN.Core.Constraints;
using WatiN.Core.Interfaces;
namespace Fundsmith.Web.Main.BrowserTests
{
public class FindByAspIdFactory : IFindByDefaultFactory
{
public Constraint ByDefault(string value)
{
// This code is never called :(
// My custom find by id code to cope with asp.net webforms ids...
return Find.ById(value);
}
public Constraint ByDefault(Regex value)
{
return Find.ById(value);
}
}
}
Edit: Extra information after the fact.
Based on me fuguring this out, (see answer below), It turns out that the way I was consuming Watin to find the elements was wrong. I was explicitly calling Find.ById, rather than letting the default action occur. So I'd reassigned the default but was then failing to use it!
[Test]
public void StepOneFromHomepageShouldRedirectToStepTwo()
{
_ie.TextField(Find.ById("textBoxId")).TypeText("100");
//Other test stuff...
}
Right, I've figured this one out, and it was me being an idiot and explicitly calling the Find.ById method, rather than letting the default action occur. It seems the test setup is a fine place to set the FindByDefaultFactory.
ie, I was doing this (wrong):
[Test]
public void StepOneFromHomepageShouldRedirectToStepTwo()
{
_ie.TextField(Find.ById("textBoxId")).TypeText("100");
//Other test stuff...
}
When I should have been simply doing this. (Without the explicit "Find.ById")
[Test]
public void StepOneFromHomepageShouldRedirectToStepTwo()
{
_ie.TextField("textBoxId").TypeText("100");
//Other test stuff...
}
Not only was this me being stupid, but I didn't include this in my original question, so it would have been impossible for anyone else to figure it out for certain. Double slaps for me.
Using FluentMigrator, the default creation of a Column using .AsString() results in an nvarchar(255). Is there a simple way (before I modify the FluentMigrator code) to create a column of type nvarchar(MAX)?
You could create an extension method to wrap .AsString(Int32.MaxValue) within .AsMaxString()
e.g.
internal static class MigratorExtensions
{
public static ICreateTableColumnOptionOrWithColumnSyntax AsMaxString(this ICreateTableColumnAsTypeSyntax createTableColumnAsTypeSyntax)
{
return createTableColumnAsTypeSyntax.AsString(int.MaxValue);
}
}
OK, I found it. Basically, use .AsString(Int32.MaxValue). Pity there's not a .AsMaxString() method, but I guess it's easy enough to put in...
You can use AsCustom("nvarchar(max)") and pack it to extension
If you often create columns/tables with the same settings or groups of columns, you should be creating extension methods for your migrations!
For example, nearly every one of my tables has CreatedAt and UpdatedAt DateTime columns, so I whipped up a little extension method so I can say:
Create.Table("Foos").
WithColumn("a").
WithTimestamps();
I think I created the Extension method properly ... I know it works, but FluentMigrator has a LOT of interfaces ... here it is:
public static class MigrationExtensions {
public static ICreateTableWithColumnSyntax WithTimestamps(this ICreateTableWithColumnSyntax root) {
return root.
WithColumn("CreatedAt").AsDateTime().NotNullable().
WithColumn("UpdatedAt").AsDateTime().NotNullable();
}
}
Similarly, nearly every one of my tables has an int primary key called 'Id', so I think I'm going to add Table.CreateWithId("Foos") to always add that Id for me. Not sure ... I actually just started using FluentMigrator today, but you should always be refactoring when possible!
NOTE: If you do make helper/extension methods for your migrations, you should never ever ever change what those methods do. If you do, someone could try running your migrations and things could explode because the helper methods you used to create Migration #1 works differently now than they did earlier.
Here is the code for creating columns incase it helps you create helper methods: https://github.com/schambers/fluentmigrator/blob/master/src/FluentMigrator/Builders/Create/Column/CreateColumnExpressionBuilder.cs
How about extending like this:
public static class StringMaxMigratorExtensions
{
public static ICreateTableColumnOptionOrWithColumnSyntax AsStringMax(this ICreateTableColumnAsTypeSyntax createTableColumnAsTypeSyntax)
{
return createTableColumnAsTypeSyntax.AsCustom("nvarchar(max)");
}
public static IAlterColumnOptionSyntax AsStringMax(this IAlterColumnAsTypeSyntax alterColumnAsTypeSyntax)
{
return alterColumnAsTypeSyntax.AsCustom("nvarchar(max)");
}
}
