[CMF-checkins] CVS: CMF/CMFCore - CMFCatalogAware.py:1.15

[Florent Guillaume]

Update of /cvs-repository/CMF/CMFCore
In directory cvs.zope.org:/tmp/cvs-serv3899

Modified Files:
	CMFCatalogAware.py 
Log Message:
Make the mixin class CMFCatalogAware be an Extension Class, otherwise we
get into the usual problems with multiple inheritance and calling
unbound methods.

The problem occurs if, from another mixin MyMixin, you want to call
CMFCatalogAware.reindexObject(self). This raises TypeError, unbound
method reindexObject must be called with instance as first argument.

MyMixin.inheritedAttribute('reindexObject')(self) can't work of course.

(The workaround CMFCatalogAware.__dict__['reindexObject'](self) still worked tough.)
