Description

Accessing a page with a Border component and a nested body a second time fails due to dequeuing problem. Find attached quickstarts (both with the same error) to reproduce the problem. First request to http://localhost:8080/test3.html succeeds while the second request to the same URL fails with the following WicketRuntimeException:

org.apache.wicket.WicketRuntimeException: Detach called on component with id 'layout' while it had a non-empty queue: ComponentQueue

{queueSize=1, queue=[[BorderBodyContainer [Component id = layout_body]], null, null, null, null, null, null, null]}
