In my page I have a rich:tabPanel (switchType="ajax") with several tabs. One of tabs contains a rich:tree - component (expand per Ajax). In my backing-bean I use UITabPanel.setSelectedTab(tabId) to select this tab. It works, but tree can not be opened any more: the reaction of server on Ajax-request (expand-Event) is not correct. Only if I manually (per mouse click) switch to another tab and back, then the tree works again.
