[Zope3-checkins] CVS: Zope3/src/zope/app/browser/security - permissionwidget.py:1.8

[Jim Fulton]

Update of /cvs-repository/Zope3/src/zope/app/browser/security
In directory cvs.zope.org:/tmp/cvs-serv18445/src/zope/app/browser/security

Modified Files:
	permissionwidget.py 
Log Message:

Changed to allow non-selection of a permission.

A src/zope/app/browser/services/componentpathwidget.py

Added a simple widget for displaying component paths when 
configuring components.

This widget is a bit unusual in 2 ways:

- It doesn't accept user input, because the component path
  is fixed.

- It behaves differently depending on whether the view (also field) 
  context is a configuration object or something else.
