For a while I have been wanting to create a TreeGrid component for Flex. The
  
basic idea is to allow a user to navigate a Tree like object within a
  
DataGrid. Well, I just finished a very hacky version 1:
  
Here are some problems with the current implementation:

  * I get strange flicker when mousing over the cells. Don't know why.
  * If I resize the right column to cover part of the Title, the title doesn't get clipped. Don't know why.
  * The code looks only for children named "product". I don't know of a way to make this generic / configurable.
  * Only supports 3 levels because I can't figure out how to do recursion in the disclosurePress function. When I tried to call another function to do recursion the recursive method never got called. Don't know why.

Other than all that, it works decently. :) Any ActionScript experts out there, please help me out. :)
