I'm using RadPaneGroupRegionAdapter (with implementation provided in some other thread). Panes are added into Items collection of a RadPaneGroup.
It works ok in Q3 but there is a problem in SP1.
When application starts every pane has it's PaneGroup positioned in docking. If some group has only one pane the header of the pane is empty. When I start dragging the pane the header appears and then works good.
Is there any workaroud?
