When I edit a cell and press Tab to move horizontally to the next cell in the same row the grid behaves wonderfully. If however, I make my next selection to another row this becomes incredibly slow (10-15 seconds). Is there any reason for this slowdown? I'm using a ArrayCollection of typed objects as my main data source. The source is between 100-5000k rows. Surely it doesn't take Flex this long to switch rows. Is there anything I'm missing?
Bump, this is a serious adoption issue preventing us from giving the grid a stamp that its ready.
Does this have anything to do with disableAutoUpdate being disabled when switching cells on same row (when you press Tab)?
