[flexcoders] First attemt at getting result back from AMFPHP - Why is it a Object

[oneproofdk]

I'm using AMFPHP 1.9B and have created a service called
"inventory.getInventoryGroups" - in the AMF service browser I see the
result just perfect. :
(mx.collections::ArrayCollection)#0
   filterFunction = (null)
   length = 5
   list = (mx.collections::ArrayList)#1
     length = 5
     source = (Array)#2
       [0] (Object)#3
         data = 1
         label = "Moduler"
       [1] (Object)#4
         data = 2
         label = "Hylder"
       [2] (Object)#5
         data = 3
         label = "Skuffer"
       [3] (Object)#6
         data = 4
         label = "Hvidlakerede bakker"
       [4] (Object)#7
         data = 5
         label = "Andet"
     uid = "42A87A93-37B2-1BCF-2D31-1E7CD7004C04"
   sort = (null)
   source = (Array)#2

But when I try to use the result in Flex (I've modified the examples
from Adobe
<http://www.adobe.com/devnet/flex/articles/flex2_amfphp.html>, using a
RemotingConnection copied from the Adobe example.

The problem is, that I get an Object back from AMFPHP and I just cant
figure out how to use that ??

This is my AS snippet :
public var gateway : RemotingConnection;
         public function initApplication():void
         {
             gateway = new RemotingConnection( gwurl );
             gateway.call( "inventory.getInventoryGroups", new
Responder(onResult, onFault));
         }
         public function onResult( result : Object ) : void
         {
             trace( result );
             selInventoryGroups.dataProvider = result as ArrayCollection;
         }
         public function onFault( fault : String ) : void
         {
             trace( fault );
         }

I'm trying to populate a simple ComboBox with the result ! What have I
done wrong  [:-/]  ?

BTW If I select result : ArrayCollection it returns an error "Cant
convert Object to ArrayCollection"

Thanks for your help,
Mark
