Binding 에러 이슈

"unable to bind to property 'XXX' on class 'Object' 
(class is not an IEventDispatcher)"


on class 'Object'

This problem occurs frequently when transferring complex objects using AMF

when the object returned from the server contains an array or array

collection of more objects.

 

One symptom of this problem is that it occurs after converting the data

request from an HTTPService call to a Remote Object call.


It turns out that Flex does not handle data returned from the AMF data

service in quite the same way as HTTPService and WebService results. With

these two later services Flex will automatically wrap Arrays in

ArrayCollection and Objects in ObjectProxy wrappers so binding will work. 


The solution is to do this same thing manually, with code similar to the

following:


function resultHandler(result:Array) {

   for(var i:String in result) result[i] = new ObjectProxy(result[i]);

   targetArrayCollection = new ArrayCollection(result);

}


Note: It may be the case that the result object is already an

ArrayCollection yet the Objects in ObjectProxy wrappers. In this case you

only need to include the for loop to implement ObjectProxy for all objects

in the ArrayCollection.
