pageflow.hasTransition(...) throws NPE if not in process
--------------------------------------------------------

                 Key: JBSEAM-2577
                 URL: http://jira.jboss.com/jira/browse/JBSEAM-2577
             Project: JBoss Seam
          Issue Type: Bug
          Components: BPM
    Affects Versions: 2.0.1.GA
            Reporter: Matthew Lieder
            Priority: Minor


I use pageflow.hasTransition(...) to determine which buttons to show on various pages. Some pages however may be gotten to outside of a pageflow, and in those cases merely calling that one method throws a NPE because getNode() returns null. Hence I'm having to check pageflow.isInProcess() at the beginning of those EL expressions. It would be nice if hasTransition(...) (and probably hasDefaultTransition() ) could be modified to just return false if processInstance is null.
