[jboss-user] [JBoss Seam] - Re: JBoss 4.0.5.GA: java.lang.NullPointerException: serialF

I managed to get things going by adding the following methods to my own MyFacesGenericPortlet.java. I'm more convinced that the portlet portition of myfaces is a little bit off sync compared to "normal" MyFaces usage.

I thought i saw
