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
