> 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.
