[Zope3-checkins] CVS: Zope3/src/zope/app/tests - test_context.py:1.5

[Jim Fulton]

Update of /cvs-repository/Zope3/src/zope/app/tests
In directory cvs.zope.org:/tmp/cvs-serv6221/app/tests

Modified Files:
	test_context.py 
Log Message:
Fixed a context wrapping bug. We were getting multiple levels of
proxies for the same object and container due to wrapping by
decorators and the publisher. The logic for detecting duplicate
wrapping was fooled by the security wrapper around the container that
wasn't in the context of the already wrapped object.
