I am trying to make a mobile app that inserts information into a database and while I have it pulling information and I have created my services, when I use the standard create service that Flash Builder 4.6 automatically makes, it just does not insert anything at all into the database.
I have tried everything and I am now with the following code:
I first create a variable array with the values of the service call
....
protected var Coordinatelist2:Coordinatelist = new Coordinatelist();
I then created a function to fill in the information. The variables SesID, Lat and Long are declared when my button is pressed.
....
protected function createCoordinatelist(item:Coordinatelist):void
{
Coordinatelist2.SessionID = SesID;
Coordinatelist2.Latitude = Lat;
Coordinatelist2.Longitude = Long;
createCoordinatelistResult.token = coordinatelistService.createCoordinatelist(Coordinatelist2);
}
After this, I then go and add the following line of code to the end of my button function.
.....
createCoordinatelist(Coordinatelist2);
Now, as far as I am concerned, this should then be writing to the database the items of SesID, Lat and Long using the created service token, but when I do this, nothing has entered into the database at all.
Am I doing something wrong here?
Sorry for the confusion but I came right.
What I found I had not done was commit my token once I created it. I simply used createCoordinatelistResult.token = coordinatelistService.commit(); and it worked perfectly.
Thanks for the feedback

I'm new here and a beginner architect. I'm helping the company I work to design our new product and since I start it, I read a lot about but is never enough.
I decided to use Mediator Pattern (with Mediatr) to call my application layer.
It's cool and I got how to work with it sometimes, but sometimes I get confused.
For example, when we publish a document on our new product, we uses a RequestHandler to do everything and check all rules it needs, it's fine and works like a charm, but, when I want just a quick data, it looks likes too much for just a simple thing.
As an example, every time the user do any kind of action on my web application, I have to check if he is still logged. We have single login per user, so, if the same user connect anywhere else, the older session expires. We do it by saving on database.
On every action of my app, I go to base and check if the session key is the same, as bellow.
var sessionKey = bibliotecaCookie.Value;
var mediator = controller.GetMediator();
var isUserSessionKeyValidRequest = new IsUserSessionKeyValidRequest()
{
sessionKey = sessionKey
};
var isValidSession = mediator.Send(isUserSessionKeyValidRequest).Result;
if (!isValidSession)
throw new UnauthorizedAccessException();
So, I have a RequestHandler (a Handler and a Request which returns a bool) just to check if the user session is ok.
When the handler catches this request, it goes to database and execute a simple rule which is "Is the passed session the same as the stored session key?".
Is it right? Is it the right approach? Did I understand it right?
Thanks in advance guys
in Flex 3.2 Having troubles converting remote object result to specific object on client side in modules.
For example I have VIPSAdmin module.
it has function
private function doResult(event:ResultEvent):void {
var data_:Array = ArrayUtil.toArray(event.result);
var result:ResultDTO = data_[0] as ResultDTO;
if(!result.isError()) {
trace(result.result);
vipsAdminDTO = result.result as VIPSAdmin;
compId= vipsAdminDTO.compId; // second time dying here
}
}
Function invoked when I get data from remote objet.
First time all great,when I unload this modeule and load it again:
data_[0] as ResultDTO;
Performs fine, but
vipsAdminDTO = result.result as VIPSAdmin;
vipsAdminDTO always null!
Even when
trace(result.result);
produces [object VIPSAdmin]
What a heck I missing here!? Looks like it just cannot do
result.result as VIPSAdmin;
even when trace and debug says it is instance of VIPSAdmin
I've figured out what is the problem, problem is that when I first instantiate something in module then in main app, somehow classes are not alined even that they are identical !
So solution is to make a fake instance in application class first, then if you use that same class to make an instance in module it will work!
I do it very simple in my main application class I just added:
VIPSAdmin;
This seems to create some sort of ghost instance, which I belie will be pickup by GC later, but will build tables of instances properly! Which solved my problem.
Not sure if this is appropriate solution ! but it sure works.
Is there a way to determine the arguments to a workflow prior to executing it?
I've developed an application that rehosts the designer, so end users can develop their own workflows. In doing this, a user is able to add their own arguments to the workflow.
I'm looking for a way to inspect the workflow prior to execution, and try to resolve the arguments. I've looked at the WorkflowInspectionServices class, but I can't seem to ask for a particular type of item from it.
Ideally, I'd like to construct a workflow from metadata stored in the database using something like:
var workflow = ActivityXamlServices.Load(new XamlReader(new StringReader(xamlText)));
var metadata = SomeUnknownMagicClass.Inspect(workflow);
var inputs = new Dictionary<string, object>()
forreach(var argument in metadata.Arguments)
{
inputs.Add(argument.Name, MagicArgumentResolver.Resolve(argument.Name));
}
WorflowInvoker.Invoke(workflow, inputs);
I might be missing something, but WorkflowInspectionServices doesn't seem to do this. It has the method CacheMetadata which sounds promising when you read the MSDN docs, but basically turns up with nothing.
Thanks for any help.
I guess that when you talk about metadata stored in the database you're referring to the XAML from the designer.
You can load that XAML as a DynamicActivity like this:
using (var reader = new StringReader(xamlString))
{
var dynActivity =
ActivityXamlServices.Load(reader) as DynamicActivity;
}
Then you've access to all its arguments through DynamicActivity.Properties.
I'm using mx.rpc.http.HTTPService to retrieve data from a web service. On the initial call to "loadWsData", HTTPservice accurately retrieves all the data.
However, on any and all subsequent calls HTTPService does not accurately retrieve the data; rather it always retrieves the first data set. I've confirmed that the web service is providing accurate data, both from web browsers and a ruby ws client script.
My code is below; any ideas on what could be the problem?
private function loadWsData(id:int):void
{
var webService:HTTPService = new HTTPService();
webService.url = "http://xxx.xxx.xxx.xxx:8080/profile/ + id;
webService.method = "GET";
webService.addEventListener(ResultEvent.RESULT, function(event:ResultEvent):void
{
var rawData:String = String(event.result);
var user:Object = JSON.decode(rawData).user; // User object always reflects the first data set retrieved.
....
....
});
webService.send();
}
Not sure what the issue might be, but I have a few suggestions on where to look.
First, there appears to be a bug in your code; the webService.url line is missing a quote mark. That could be messing up the URL you think you are sending. Odd, though, because I don't think what you have shown would compile, so I suspect this is just a cut-and-paste error when you posted this to StackOverflow, but I would trace out that URL just to be sure.
Also, I don't see code to remove the event listener (although it could be in the code you have abbreviated with ellipsis). Is it possible that there are lingering event listeners that are firing in addition to the ones you expect? If the original event listener fires, it will fire with the original data.
Another suggestion: instead of using a closure, try pulling it out to a separate function. That shouldn't be the issue, but maybe scope is playing a role here.
You could try to POST your results.
You might also add an event listener for FAULT, and see if there are any errors being thrown by your service request.
My problem, simplified:
I have a dataGrid with a dataProvider "documents"
A column of the datagrid has a labelFunction that gets the project_id field of the document, and returns the project name, from a bindable variable "projects"
Now, I dispatch the events to download from the server the documents and the projects, but If the documents get downloaded before the projects, then the label function gives an error (no "projects" variable)
Therefore, I must serialize the commands being executed: the getDocuments command must execute only after the getProjects command.
In the real world, though, I have dozens of resources being downloaded, and those command are not always grouped together (so I can't for example execute the second command from the onSuccess() method of the first, because not always they must be executed together..)..
I need a simple solution.. I need an idea..
If I understand you correctly, you need to serialize the replies from the server. I have done that by using AsyncToken.
The approach: Before you call the remote function, add a "token" to it. For instance, an id. The reply from the server for that particular call will then include that token. That way you can keep several calls separate and create chains of remote calls.
It's quite cool actually:
service:RemoteObject;
// ..
var call:AsyncToken = service.theMethod.send();
call.myToken = "serialization id";
private function onResult(event:ResultEvent):void
{
// Fetch the serialization id and do something with it
var serId:String = event.token.myToken;
}
