Hi Sven,
With bf96810d00d0eb916a0425dc413afef6f2fb5b57 you added a call to #updateTab()
in TabbedPanel#onBeforeRender().
This causes a call to ITab#getPanel() at line 427 for each render of the
TabbedPanel and thus re-creates the panel for the selected tab and looses the
state I may have in the previous panel instance.
I believe this is a bug.
It is easy to reproduce with Wicket Examples -
http://localhost:8080/ajax/tabbed-panel. Click on a tab and you will see that
ITab#getPanel() is called twice - once by setSelectedTab() and once by
onBeforeRender(). The real problem is when the TabbedPanel itself is repainted,
then onBeforeRender() reconstructs the selected tab's panel.
