           Summary: deleting open composite actor may delete model
           Product: Kepler
           Version: 1.x dev
          Platform: Other
        OS/Version: All
            Status: NEW
          Severity: major
          Priority: P2
         Component: interface
        AssignedTo: berkley at nceas.ucsb.edu

Under certain circumstances, deleting an open composite actor may result in
deleting the remainder of the model. Here are steps to reproduce this:

1. start kepler
2. add some actors to canvas
3. add a composite actor to canvas
4. file->save
5. open composite actor (so that a new window displays its contents)
6. without closing composite actor window, go back to top level canvas, and
delete the composite actor
7. in the top level window, file->save
8. close composite actor window. the dialog to save changes will pop up; select
save. (note the file is the same as the top level file name in step 4).
9. now close top level canvas

When you re-open the model, the top level contents are replaced by the empty
contents of the composite actor.

I would guess that step 6 should close the composite actor's window, so that
step 8 is not possible.
