Sebastian Gooren commented on WICKET-6405:
------------------------------------------

Hi!

Since we just ran into the same issue, I have been playing around with this.

Please note that the javadoc on the Border class itself still (wrongly) states (in wicket 8.4.0):
{quote}In case the body markup is not an immediate child of border (see the example below), then you must use code such as <code>someContainer.add(getBodyContainer())</code> to add the body component to the correct container.
