[CLOSED] Problem using GridPanel with EditableGrid, GroupingView and GroupCommands
Hi,
My program is throwing an exception when I use a GridPanel combined with EditableGrid, GroupingView and GroupCommands.
To identify the errors follow these steps:
1) Click a menu item in the group command 'Aprov'
OR
2) Change the value of the column 'Aproved' to 'Yes', focus any other control, change the value to 'No' and focus any other control.
It seems to be a cache error, but I don't know how to solve. This error only apears if I use the '<ext:CommandColumn />' tag. When this block is commented everything works fine.
