Yes, and this is why I always advise against directly binding to lastResult, it is hard to debug. If you bind to an instance variable, and then use a result handler function to assign the event.result (properly cast) to that variable, you have the opportunity within that handler to examine the structure of your data. It might not be exactly as you think, and you must be exact in your references into it. If you are using e4x XML, toXMLString() will show you precisely what you have.

Most of them contain a top-level object above any array-like structure, so you may need to do something like this: <mx:ArrayCollection id="myProvider" source="{wsAlice.findUsers.lastResult.nameObject}"/> HTH, Ben --- In flexcoders@yahoogroups.com <mailto:flexcoders%40yahoogroups.com> , <[EMAIL PROTECTED]> wrote: > > Hello all, > > I believe I'm following the docs precisely (the "Binding a > result to an ArrayCollection object doc" in the Flex IDE > Help), but my app isn't working.
