Hi Darron,
Change mx:dataProvider to controls:dataProvider
Because dataProvider is a property of the ComboBox, it should use the same
namespace as its parent.
Cheers,
Ali

Subject: [flexcoders] Extended ComboBox can't use mx:dataProvider /
I've run into an interesting situation. I needed to extend the
combobox, and in doing so, I'm not longer able to nest the
mx:dataProvider tag.
For example, the following code doesn't work.
controls:MyCustomComboBox
mx:dataProvider
mx:Array
mx:StringItem 1/mx:String
mx:StringItem 2/mx:String
mx:StringItem 3/mx:String
/mx:Array
/mx:dataProvider
/controls:MyCustomComboBox
If I replace my custom combobox with mx:ComboBox, the above code works
fine.
However, the following code *does* work as expected:
mx:Array id=dp
mx:StringItem 1/mx:String
mx:StringItem 2/mx:String
mx:StringItem 3/mx:String
/mx:Array
controls:MyCustomComboBox dataProvider={dp} /
So, the data provider isn't broken at all, but rather the compiler just
can't process the nested dataProvider tag. The error message is:
Error: Don't know how to parse element
http://www.macromedia.com/2003/mxml:dataProvider;. It is not a known
type or a property.
... which is odd, because as a subclass of ComboBox, it shoudl be one in
the same. I tried extending via an ActionScript file and an MXML file,
and both yielded the same results.
Is this something that I would need to modify the schema for to be able
to nest the mx:dataProvider tag in my extended combobox component?
Anyone have any ideas? It looks like a bug to me, but I don't think I
know enough about it to say that it is for sure.
On a related topic, the regular combobox doesn't seem to respect
Stage.height when loaded into another Flex .swf. I thought this was
fixed? I have a ComboBox opening below the Stage, and no amount of
_lockroot seems to solve it.
