Re: [flexcoders] Null error when using specifying itemRenderer on dataGridColumn
you need to set rendererIsEditor=true in the code, the RTE will be gone.ThanksHarishOn 4/28/06, Matt Chotin

Note that the error is for the item editor
when you say it's the renderer that you change to fix it. Sounds like a
bug to me… I'll forward it inside.

Subject: [flexcoders] Null error
when using specifying itemRenderer on dataGridColumn
I've been struggling for some time
now (and I'm assuming this must just be so brain-dead simple)...
Trying to set an ItemRenderer and ItemEditor on a datagridColumn. For
certain ItemRenderer's, I am getting a null error. (using Flex 2 beta 2)
NOTE: I am not trying to use these as my actual renderer and editor classes as
they don't really provide anything at all above the defaults.. but I noticed
this gives the EXACT same error. (My actual renderer extends from
Canvas...)
If you change the itemRenderer to mx.controls.Label, then it works fine.. and
oddly enough Text extends Label. Any ideas?

Random shot, try importing
mx.controls.Text and mx.controls.TextInput? I think it should have been a
compiler error if it was necessary but
Note that the error is for the item editor
when you say its the renderer that you change to fix it. Sounds like a
