Andi Huber commented on ISIS-1963:
----------------------------------
Pre Wicket-8 behavior [1] in Wicket's RequestHandler was simply to ignore cases
of 'page is not the same as the one this handler has been created for', which
do now result in an IllegalArgumentException being thrown.
So a quickfix on our side could be to simply catch these
IllegalArgumentExceptions and ignore them.
