Hello, I'm trying to get a Wicket 6 app running as a Portlet in JBoss GateIn 3.6 using the wicketstuff-portlet lib ( https://github.com/wicketstuff/core/tree/master/jdk-1.6-parent/portlet-parent ).
So far I have managed to get the Wicket quickstart app running, i.e. I can display simple things like a "Label" in the Wicket portlet. However, as soon as I add a "Form" to my page I get an Exception (see below). Has anyone maybe a running example or can point me to some documentation? Things I found on the web seem to be mostly for Wicket <1.5 or specific to Liferay. Thanks in advance.
