Thanks Ken, Jacque,
I know the result indicates an applescript problem, I should have clarified a
bit by asking if the user could do something in his system that would cause the
applescript problem.
Jacque the problem sounds similar. My app creates a folder in the library/app
support folder. That was failing so I sent him a stack that tried to write a
simple folder to the support folder without all the other stuff the original
app was doing. It failed but reported its progress to the point of using
revcopyfolder. It created a folder and reported the existence of it afterwards.
Then I tried to revcopyfolder from a folder stored in the .app package and it
fails. I tried writing to the defaultfolder where the simpletest app was and
the same result - execution error.
Based on what you are seeing, perhaps the original report of the existence of
the folder is incorrect so naturally the following call to revcopyfolder fails.
The problem would then be in the call 'create folder'. Should we be looking
there instead?
Thanks
Ron
