i'm having the same problem here, and what really puzzles me is that if i press the 'back' button, then repeat the what i did before, no exception is thrown! most of the time, it just works nicely! and instead of "org.jboss.seam.security.identity", sometimes i'm also getting "Cannot get value for" "org.jboss.seam.core.actor" and "org.jboss.seam.core.jbpmContext". so ... any clue?
