[Zope-dev] Bug in TransparentFolders ???

[Andre Schubert]

Hi,

after searching the soures if found a way the point of disaster.
in TransparentFolderPatch i changed the line:
if tpids and not self._v_no_transparent and name[:3] != '_p_' :
to:
if tpids and not self._v_no_transparent and name[:3] != '_p_' and
name[-11:] != '_Permission':
which means to me the if there is a TransparentFolder then don't acquire
its Permissions only Acquire its Objects.
Is this right or did i forgot something???

thanks as
