Zope 2.2.1, ZPatterns 0-4-1snap1, with some small patches.
I'm adding a dataskin-derived ZClass instance underneath a Customizer
folder.
The Customizer has a SkinScript plug-in.
When I try to add a new ZClass instance, I get an exception that I can
trace to the fact that DataManager's _objectAdding method is trying to
call _objectAdding on a Compute object.
DataManagers.py line 29:
def _objectAdding(self,client):
for ob in
self._uniqueProviders(('attributes','sheets','handlers')):
ob._objectAdding(client)
I've temporarily fixed the problem with a test to see if the
_objectAdding attribute exists:
def _objectAdding(self,client):
for ob in
self._uniqueProviders(('attributes','sheets','handlers')):
if hasattr(ob, '_objectAdding'):
ob._objectAdding(client)
On deleting a Dataskin object, there was no error in the Zope Management
interface, but the following was logged to the console:
2000-08-28T15:05:08 ERROR(200) Zope manage_beforeDelete() threw
Traceback (innermost last):
File /lib/python/OFS/ObjectManager.py, line 327, in _delObject
(Object: PlugInBase)
File /lib/python/Products/ZPatterns/DataSkins.py, line 303, in
manage_beforeDelete
(Object: doo)
File /lib/python/Products/ZPatterns/DataSkins.py, line 162, in
_objectDeleting
(Object: doo)
File /lib/python/Products/ZPatterns/DataManagers.py, line 34, in
_objectDeleting
(Object: Transactional)
AttributeError: _objectDeleting
Therefore, I've patched _objectDeleting similarly.
The SkinScript method is:
WITH SELF COMPUTE
title="foo", fish='%s, (%s)' % (id,name)
I suspect this is not the best way to solve the problem, though. Should
compiled SkinScript support these methods?
