Sorry for the Table Population Hack,
I am expecting to edit column 0 and when I click/Press on a row that exists
within the non scrolled region all is well.
Scroll down then click/press a cell to edit (casted as TextField) and the
Table scrolls back to top.
As soon as The Table scrolls back to top, the cell I pressed and was going
to edit, looses focus and of course would execute an actionEvent (Not Shown
Here)
How do I prevent the scrolling back to top when I press a cell in this case?
Thanks In Advance!
