I want to show summary in Grid dockItem. I can insert there any component. I give that component to summary view property. But it can't apper there and throw error: "Cannot call method 'getColumnsForTpl' of undefined". For example I tried to show it in xtype container. I know, that it is impossible, to show it in simple container. What layout/component/template/another action I need to do, to take my summary in that dock?
