Hi.
After a while I tried to checkout again the RPAD portlet, but it seems its not functioning at the moment. It returns just null and throws a null pointer exception. I debugged a bit it seemed that the exception is thrown some where around the JSF-Bridge FacesPortlet line 507 context.release() and MyFaces ServletFacesContextImpl line 321 FacesContext.setCurrentInstance(null).
http://portals.apache.org/bridges/multiproject/portals-bridges-jsf/xref/org/apache/portals/bridges/jsf/FacesPortlet.html#507 http://myfaces.apache.org/impl/xref/org/apache/myfaces/context/servlet/ServletFacesContextImpl.html#321
I'm not too familiar with JSF portles, or the bridges, nor the MyFaces, so can't say which of these is causing the issue. But it seems that it does not work either in the 2.1 release version.
There is a compatibility matrix for MyFaces at http://wiki.apache.org/myfaces/CompatibilityMatrix is there is some issues like that. At least the bridges were using 1.1.4 and Jetspeed 1.1.0 versions. 

Is anyone using these at the moment? Should the trunk versions work?


I built j2 trunk by maven1, and it worked.

But, in my opinion, myfaces and jsf bridge have several issues on portlet.
So, I wanted to replace it with Teeda before J2.1 release, but I could not
have time to do.. Teeda is JSF implementation and I'm working with the open
source community.

Thanks,

Probably this is more of a dev list issue..
