How, exactly? I can't pass parameters into or out of the renderer.

You cannot access the comboBox itself, you can only >access the dataProvider. From inside the Renderer, I can access the dataProvider? I swear I tried that once already, and it didn't work.

No problems when scrolling, that I've noticed (but maybe I haven't added enough items to cause a problem -- I'll have to try that. The problem occurs when I delete an item from the ArrayCollection that's acting as the DataProvider. > > >**All interactive itemRenderers must update the dataProvider when >changed and must override the set data function to use the >dataProvider item to set the renderers state**** Got no idea what you mean by that.

I did do a search, to see if anyone has written something like this in the past. But I couldn't find anything close. I need two always-un-editable columns, and one column that allows some records to be edited and not others. I figured a custom ItemRenderer ComboBox with Enabled turned on or off as needed would suffice. But I guess it's far more complicated than just that? Why doesn't the documentation on custom ItemRenderers mention this? I'm terribly confused now. Can anyone help un-confuse me? :-) Thanks, Laurence MacNeill Mableton, Georgia, USA
