Subject Facelets: Back button, then nav-link click produces NPE
Date Thu, 26 Apr 2012 19:39:50 GMT

Hi, I'm using MyFaces + Facelets + Trinidad + WebLogic 10.3.5.

When trying to use the back button to backtrack to previous pages, it seems
the pages themselves are in the browser chache and do display alright.  Yet,
when I try to use any Trinidad link or command button, I get a
NullPointerException.  This is happing on every page on the site.  Yet, if I
hit the back button, then, refresh the resulting cached page, then the
forward navigation items work just fine.  What is going wrong here:

java.lang.NullPointerException
