What is serialization support like for the new Vector class? I have a Vector.<GameMove> which I'd like to serialize into a ByteArray. GameMove is a custom class. I presume it's necesssary to call registerClassAlias() on GameMove, but do I also have to register Vector.<GameMove>? It's it it's own distinctive type, or is it kinda composed of those two types?

I was wondering if it is possible to do custom serialization of Arrays/ArrayCollections in as3 via amf. To be more specific, i want to be able to pool objects on the client so that im not instantiating new objects every time i make a RemoteObject call. I tried using IExternalizable but that only lets me serialize the objects myself not instantiate them. The flash player is still instantiating objects itself and them letting me set the object state via readExternal.
View 3 RepliesIs there any way, without having the creator of the object implement any special functions (no specific serialization functions) (however, they can use annotations), to have Flash serialize a generic, possibly deep (objects within objects within objects, etc, etc, etc) object?
View 2 RepliesI'm using BlazeDS to remote some Java objects that I'm consuming in a Flex application. I'm getting a type coercion error with one of my classes that I can't for the life of me figure out. I have other classes that are working fine using the same data types, and I've gone over my mapping a dozen times. I'm following all of the necessary conventions for getters and setters as far as I know...
Anyhow, my question is: how can I debug this problem? Running the Flex app in debug mode spits out some generic errors to the console that don't really help much (TypeError: Error #1034: Type Coercion failed: cannot convert Object@5d1d809 to valueObjects.SomeClass.).
If I want to pass in a vector to a function, a vector of any object specifed would it be someVetor:Vetor.<T>? beause FB 4.5 sais T is undefined.
View 10 Repliesthe applicable differences between an ArrayCollection and a Vector in flex? I'm unsure if I should be using one over the other. I saw that Vector is type safe and that makes me feel better, but are there disadvantages?

I have a service which returns an Array of ObjectProxy objects. I would like to cast this to a custom object (a value object) and create an ArrayCollection. How can I do this?ited:I am using Django and PyAMF for the backend. I had to write a custom SQL query and I am wrapping the resulting records in ObjectProxy and sending the whole result as an ArrayCollection.Here is my client side code:
[ArrayElementType("SessionVO")]

I have been trying to test my application to make sure that all the important classes can serialize/reload themselves properly (especially those which implement IExternalizable):
[Test]

var myobj:MyObject = new MyObject();[code]....
And I would like to be warned when I try to serialize a strongly-typed object which does not have a [RemoteClass] set (because that almost certainly represents a bug in my code).So, is there any way to configure the AMF serializer to give warnings?Also, it seems like this might be possible using services-config.xml... But the documentation seems to imply that services-config is channel-level, and I'd really like it if my unit tests could run without talking to the server (and I'm not using LCDS, so a bunch of the services-config wouldn't apply to me anyway).
Is it possible to receive custom generic typed objects through AMF? I'm trying to integrate a flex app with an existing C# service but flex is choking on custom generic typed objects. As far as I can tell Flex doesn't even support generics, but I'd like to be able to even just read in the object and cast its members as necessary. I basically just want flex to ignore the <T>. I'm hopeful that there's a way to do this, since flex doesn't complain about typed collections (a server call returning List works fine and flex converts it to an ArrayCollection just like an un-typed List).
The custom C# typed class
public class TypeTest<T> {
public T value {
get; set; }
public TypeTest () {
}}
The server method returning the typeTest
public TypeTest<String> doTypeTest() {
TypeTest<String> theTester = new TypeTest<String>("grrrr");
return theTester;

writeObject creates ByteArray that I am able to print but when i get it back and add child, I am not able to get the panel and it's children.

I recently came into a situation when sending a nested object from Java to Flex via a HashMap the Objects were null. More precisely:final Map< Integer, List<String>> tempMap = new HashMap<Integer, List<String>>();would send the keys as integers but the values were all null.But when sending the same with String keys:final Map<String, List<String>> tempMap = new HashMap<String, List<String>>();the objects came thru.Are there any restrictions in BlazeDS serialization when using complex types as keys?

I've been looking at various questions in StackOverflow and in other sites, but I have not seen a library that a) generates actionscript code given XSDb) serializes to and deserializes from XML using the generated classes. In Java world this is JAXB. I have a set of large XSDs, based on which a web service is producing XML output. I don't want to write actionscriptclasses by hand, that'd be huge piece of work. Having source code in actionscript since writing code based on runtime binding of xml/json to objects is much more error prone compared to having proxy like classes.
View 1 RepliesI'm trying to use the native flex serialization/deserialization process to save/load state of a workspace in flex.

The event.data that I write to the byte array is not reconstituted into a MyWorkspace object even though it is exactly what I wrote to the file.There has to be a way of making a MyWorkspace object from the data, but I can't figure it out.

I'm creating a simulation in which a large number of objects are added to vectors and then taken away in random order (as more are being added). To remove the objects, I splice the object from the vector it's in, and notify all the other objects that an object ahead of them was removed so they can change their indices accordingly. As far as I know, the objects have no other references (I think), and within the object, I set everything to null. I read somewhere that you can't put "delete this" in the class, so I didn't bother with that. Will this be sufficient to get the object garbage collected, or should I do something else? What are the best ways to get something like this garbage collected?
View 2 RepliesI want to arrange certain objects from a vector/array into a gird
Currently, I know how to do this during the creation of the objects.
Here's the grid function I've created:
function ArrangeInGrid(uiRow:uint, uiCol:uint, iOffsetX:int, iOffsetY:int):void
{
for(var i:uint = 0; i < uiRow; ++i)
{
[Code].....
Now I want to be able to apply the same logic of arranging objects in an array/vector in to a grid, how do I do it?
Or suggest a more efficient way to do so (if you have).
Notes:
I want it to be flexible in how many rows and columns the grid can have. The vector I'm using already has the cards in it. I can't just push the cards into the vector cuz of the way I manually created my cards.
I know there are different situations where one would be better than the other, but I'm comortable with a generalized statistic of... How much faster is blitting than using vector Sprite objects in Flash?
View 2 RepliesWhat I want is to sort a Vector array of objects(not primitive), based on a propery(Number). (think character.zDepth). Generally the same thing as the sortOn function of Arrays, except that we don't have that for Vectors.

This is NOT duplicate of my earlier post (its is slightly different)But this is similar issue with similar error but its not the same error The error I am getting now is below while dispatching the custom event from my custom component
TypeError: Error #1034: Type Coercion failed: cannot convert events::MapEvent@a74ab51 to flash.events.MouseEvent.
dispatchEvent(new MapEvent(MapEvent.CLICKED_ON_MAP));
Note: The error in my earlier post is giving below error message
Type Coercion failed: cannot convert flash.events::Event@81ecb79 to com.events.ShopEvent
The difference here are two things, the earlier error is while converting flash event to custom event and now this one is while converting custom event to flash event and secondly, I have no clue why it is trying to convert to the mouseevent where I am just dispatching my custom event with proper listeners.
This is my custome event

Right away i just try to explain my problem: Using BlazeDS i got the following Javaclasses:
[Code]...
Then i got a Flex service class calling BlazeDS and executing the getCategories java method. Since Flash dosn't seem to understand typed arrays, the result from that method which i get back in flex is a simple array of untyped objects (the mapping dosn't seem to work here, even tought the class category exists in flex and has the same properties).
thats the first thing. but however, i'm converting the untyped objects manually into objects of the category.as class. the second thing is that categories have child-categories within the java object, which are also ArrayLists of the type category.java. the problem about that: my result event object only contains the first level of categories, looking into them the children are allways null. i dunno why they are empty, since they ARE part of the java object category.
and the third thing (the strangest by fast), you maybe noticed i named the properties of the category.java class strange, like idCat and nameTest instead of simply id and name. why that? because the property names of my flex result objects dont seem to change when i change the java objects properties names (result object properties are named "id" and "name" but the java class object properties are named "idCAT" and "nameTEST"). that it REALLY strange, since if i set the properties, like you see at nameTEST = "TESTNAME" it IS recogniced by flex, only the proertyNAMES dont seem to be recognized at all.

The spark panel component for example can be written like this
<Panel title="Skinny">

The motivation here is that I can now create a couple different skin files to change the look and layout of those subgroups. Reading source of the spark panel, there are some calls within the mx_internal namespace such as getMXMLContent() which is a method of the spark group component, but which I have no access to.
Does the description above make sense? How can I create custom 'contentGroups' in my custom Flex4 component that can use nested mxml child components? Should I approach this a different way?

I have the following situation:I have an event handler, that displays small messages in my application's statusbar.These messages get passes through by dispatching events from custom components.A simple message could be like "HTTP Error" or so.Now, the main event listener, in the main application file, listens to the event dispatched by any custom component,but seems to refuse listening to events dispatched by custom AS classes.Here is my code for the custom event:
package main.events
{
import flash.events.Event;[code]..
So to sum it all up:
- The event listener listens to the custom event dispatched by any custom component.
- The event listener does not listen to the custom event duspatched by an AS class.
Those who wonder, the event really gets dispatched, that's why I added a trace call.
