           Summary: add output port to Throw Exception
           Product: Kepler
           Version: 1.x dev
          Platform: Other
        OS/Version: All
            Status: NEW
          Severity: enhancement
          Priority: P4
         Component: actors
        AssignedTo: berkley at nceas.ucsb.edu
        ReportedBy: soong at nceas.ucsb.edu
         QAContact: kepler-dev at kepler-project.org


In some of my workflows, I have an actor that checks that certain components
are installed and working before trying to run the workflow.  If things are
missing, it uses the Throw Exception actor to stop execution and display an
error message.  Right now, it's possible for the director to schedule the
entire workflow before the error check, even if I use the "check" actor as a
trigger.  I just want some way to convince the director that needs to fire the
Throw Exception actor before the rest of the workflow.
