Provides SecureOrderedMultiSelectWidget which fixes an acquisition bug in OrderedMultiSelectWidget in zope.app.form.

Project Description

Introduction:

This package fixes a Plone/Zope2 Acquisition bug for the OrderedMultiSelectWidget that appears in zope.app.form.browser.itemswidgets.py line 556.

Note: The itemswidgets.py module has been moved to zope.formlib in newer versions of zope/ztk.

The OrderedMultiSelectWidget is used automatically for zope.schema.List type fields.

How do I know if this bug affects me?

If you get errors in your traceback or error_log similar to the one below, you might have be affected: (XXX is variable)

Line 166, Column 8
Expression: <PathExpr standard:u’view/selected’>

Module zope.app.form.browser.itemswidgets, line 562, in selected
Module zope.schema.vocabulary, line 124, in getTerm
LookupError: XXXX

Installation:

Just make sure that collective.orderedmultiselectwidget is installed via the plone control panel or the portal_quickinstaller tool in the ZMI.

Afterwards it should just work.

Why not fix the bug in zope.app.form and zope.formlib?

zope.app.form and zope.formlib are Plone/Zope2/Acquisition agnostic. They do not depend on Acquisition and no one will want them to.

A bug might however be contributed to plone.app.form. I’ll contact the dev-list, but for now, this is a bug-fix package for people being affected on in-production systems.
