Oh, I see the cellcontextmenu event now when I capture on the grid's view and not just the grid. Thx for pointing that out - will come in handy.
Looking forward to cellcontextmenu promotion to the panel.Table and that headercontextmenu event.
Thanks again for listening to the community. This sort of dialog on top of the excellent JS framework is why I'll always lobby for my company to license with Sencha.
