I'm using a product python class that inherits from CatalogAwareness and CopySupport. The automatic indexing and unindexing on creation and deletion works fine. When a cutted object is pasted into another folder, manage_beforeDelete raises Error Type: AttributeError Error Value: aq_acquire. Debugging brought up, that absolute_url() doesn't work when the object is marked as cutted. The acquisitiontree is traversed up to th root-application object. Zope.absolute_url() tries to call self.aq_acquire('REQUEST').script. I didn't overwrite any of the involved methods and have no idea what else could have such a bad influence on the Application object. When a object is explicitly deleted, manage_deforeDelete() works well. I would be very glad if someone could help me out. Thanks, Alex
