Populating an ArrayCollection property using [RemoteClass]

OK, I am passing a complex object from my .NET library to my Flex application via WebOrb. In order to automatically translate, I am using the [RemoteClass] meta data tag as follows:

[RemoteClass(alias="test.PlanVO")]
public class Plan
{
    [SyncId]
    public var id:int;

    public var Name:String;
}

This works absolutely fine, until I try to extend the Plan class to contain an array of complex items:

.NET:

public class PlanVO
{
    public int id  { get; set; }
    public string Name { get; set; }
    public List<PlanElementVO> children { get; set; }
}

public class PlanElementVO
{
    public string elementName { get; set; }
}

ActionScript:

[RemoteClass(alias="test.PlanVO")]
public class Plan
{
    [SyncId]
    public var id:int;

    public var Name:String;

    public var children:ArrayCollection;
}

[RemoteClass(alias="test.PlanElementVO")]
public class PlanElement
{
    public var elementName:String;
}

In this case, even when children are returned by the .NET library, the children property of the ActionScript Plan class is null.

I have tried changing the children field to a property like this:

private var _children:ArrayCollection;
public function get children():ArrayCollection 
{
    return _children;
}
public function set children(o:*):void
{
    if(o is Arr开发者_开发百科ayCollection)
        _children = o;
    else if(o is Array)
        _children = new ArrayCollection(o);
    else
        _children = null;
}

but the set function never gets called.

What can I do to get the children into my Flex app in this way?

Thanks!

It's no surprise to me that the set method s never called. The object should, theoretically, return from the server with the items already set.

That said, I did not think that an ArrayCollection would match to a server side object. Try using an Array in Flex. In .NEt you should use one of the "supported" types. If List is an implementation of IList, then you're probably fine.
