 Right now I'm playing around with the RemoteClass feature with a few
 ActionScript classes.  What I've noticed is that if I have a single 
object I
 can nest AS classes.  So if I have two AS classes foo and bar I can 
have the
 following work
 
 [RemoteClass(alias=com.ca.foo.Foo)]
 public class foo
 {
 public var ID:int;
 public something:bar;
 }
 
 this gets converted correctly when I call a function that returns a 
foo.
 bar is correctly identified as a bar and is placed as such.
 
 
 Now here's where I've run into trouble.  If I try to have an array 
of bars I
 can't figure out how to get this to work correctly.  Example:
 [RemoteClass(alias=com.ca.foo.Foo)]
 public class foo
 {
 public var ID:int
 [ArrayElementType(MenuItemSetting)]
 public something:ArrayCollection;
 }
 
 This does not work.  When I return from the remoteObject call foo 
is done
 correctly up to the ArrayCollection.  The ArrayCollection has 
objects in it
 instead of MenuItemSettings.
 
 Here is the result function that has objects for the 
ArrayCollection Items
 
 public function Success(event:ResultEvent):void
 {
 var test:foo;
 
 if(event.result != null)
 {
 test = MenuItemPackage(event.result);
 }
 }
 
 However, here's where it utterly baffles me.  In my result function 
if I add
 this one line of code to it, the objects for all items in the 
collection
 become type bar.
 
  public function Success(event:ResultEvent):void
 {
 var test:foo;
 
 bar(event.result.something[0]);
 
 if(event.result != null)
 {
 test = foo(event.result);
 }
 }
 
 
 I do realize this will have issues if there are no elements in the
 ArrayCollection or if the result is null.  What the heck is happing 
here?  I
 can even put the breakpoint in before the bar(event.result.something
[0]);
 and look at result and it is typed to the bar.
 
 My other question is, can this be done automatically?  Or do I need 
to leave
 in the bar(event.result.something[0]);?
 

I'd be inclined to guess that the only hard reference to bar in the 
class that calls the service is that one line where you call
 bar(event.result.something[0]);

Try doing this:

private var dummy:bar;

And see if that fixes the problem
