Comment 7 for bug 143399

Uploaded: test_wfbug.py

I finally managed to produce a test case which demonstrates the problem.

The critical thing seems to be that the View permission at the point when the script is invoked must not be inherited.

If you run this test file (in a directory such as CMFPlone/tests) then on my system it comes up with:
Unauthorized: You are not allowed to access 'object' in this context

Either commenting out the line which assigns proxy role to the script or commenting out the sdef.setPermission line will allow the test to pass.
