           Summary: "change failed" error while copy/paste-ing an ImageJ
                    actor
           Product: Kepler
           Version: 1.x dev
          Platform: Other
        OS/Version: Windows XP
            Status: NEW

This seems to affect only Windows systems and has to do with saved values in
the fileOrURL parameter in the ImageJ actor.  It seems to occur when the model
run folder contained within the .kepler folder is deleted.  To cause this to
occur under Windows, create a trivial model (1 SDF, 1 RExpression, 1 ImageJ
hooked to the RExpression's graphicsFileName port), run it once, then save it. 
Close Kepler, clean-cache, and open the model again.  The actor cannot be
copy/pasted.

The workaround is simply to delete the value in the fileOrURL parameter or find
a linux/OSX system.
