RE: [flexcoders] Dataprovider and events
I just got done adding that in. The result event was moved to the
CallResponder.
Thanks!

Instead of using creationComplete, you might want to wait until you get
a resultEvent from the server.

The combobox cbGroupSelect pulls its data from the provider first which
gives the index fields for the list object. I'm doing creation_complete
on the list object, but the object is created before the data provider
for the combobox has filled its data.
Here's the dump:
TypeError: Error #1009: Cannot access a property or method of a
null object reference.

Post the entire stacktrace so we can see why it throws.

I've got a listbox that depends on a combobox to load

Any ideas?
