Re: [flexcoders] ComboBox ItemRenderer

[mark goldin]

Not sure I understand about ownerData. Is it a hard coded dataProvider name for 
DG? I am working on a generic solution, I can't use hard coded names. Sorry, if 
I am misunderstanding your solution.

  What is an actual design pattern for that?
   
  Thanks much for help.
