Following from a discussion about https://issues.jboss.org/browse/DROOLS-2874 it was agreed that editing cells (header or body) in the grids should respond to single-click and not double-click.
- Not possible edit multiple cells by hold CTRL and click on multiple cells
- Click column/row leading cell discard edit dialog
Edit can be discarded by escape DROOLS-2932
- Edit can be discarded by click to canvas
- Invoke edit of cell, return do DRG
- Save and reopen
- Undo redo of editation
