Alex Harui commented on FLEX-34060:
-----------------------------------
IMO, the issue is that you are trying to resize the row as the editor appears.
I don't think the DG was designed to handle that.
So, solutions to try probably involve resizing the row before starting the edit
session. There are events like ITEM_EDIT_BEGINNING that can be used to cancel
the start of an edit session, then you can try resizing the row, scrolling to
the new bottom, and then starting the edit session by setting
editedItemPosition (and setting some flag so you don't cancel it in your
ITEM_EDIT_BEGINNING handler. Another possibility is to try adding a fake blank
row so the editor never has to appear on the last row.
