Have you tried to put a breakpoint in order to look in the debugger the structure of your result?
You might also have a look with ServiceCapture (http://kevinlangdon.com/serviceCapture/).
It's a "must have" tool for debugging RPC requests. 
 
The result is probably an array.
So you might have to do :
model.categoryList = new ArrayCollection(event.result);

Matt,

Thanks for looking into this.

I am taking another approach to solve this problem.  UsingBenoit's PhoneCairngorm configuration. It seems to be working, however,I am getting a compiler error message:

Implicit coercion of a value with static type 'Object' to a possibly unrelated type'mx.collections.ArrayCollection'

Note: the red line in thecode below is the problem.  The trace output returns an array ofobjects of type  categoryVO. 

BTW, I also tried to cast :

model.categoryList = ArrayCollection(event.result)   but the same error from the compiler.
