           Summary: changes made to workflows during dialogs before
                    committing
           Product: Kepler
           Version: 1.x dev
          Platform: Other
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: P2
         Component: general
        AssignedTo: berkley at nceas.ucsb.edu
        ReportedBy: soong at nceas.ucsb.edu
         QAContact: kepler-dev at kepler-project.org


When I make changes to an actor through the dialog, it seems like the changes
are made to the workflow immediately, before the "Commit" button is clicked.

For example, create a workflow with an EML 2 Dataset actor.  Make sure Kepler
has not already authenticated with KNB.  Now edit the EML 2 Dataset actor to
reference a data package that requires authentication.  The KNB login window
will immediately pop up, even though no changes have been committed.  Dismiss
the window in some way.  Now click the Help button and close the help window. 
The dialog will have disappeared.  Open the actor dialog again, and the change
will be there.

I should point out that the "Cancel" button does seem to work, but I suspect
(based on debugging comments and comments in code) that this acts by reverting
the changes already made.

I've seen this for sure on EML 2 Dataset and RExpression, since changes to one
trigger visual feedback and I've mucked around in the code of the other.  I
suspect this is a general problem, though, and it may be a result of the
underlying ptolemy design.
