can you try | taskInstance.end(tr.getName()) | and see if it makes a difference? (I doubt it but nevertheless) And set the debug level for the TaskInstance class. If that does not result in anything, make a *full* unittest with *everything* embedded (the processdefinition as a string) so I can test it?
