Collapse / Expand grouping feature in a grid
in my application there's a center region which contains a grid with groupingFeature.
After showing this all Groups are collapsed. Now i would like to integrate a button in toolbar where user can collapse/expand all groups.
I found this post and used code from #2 but it doesn't work.
FF shows this error:
view.el is undefined
Can anybody help?
