I have a Zclass newsdoc, with base classes of catalogaware and object-manager.. Everything worked nicely, it added and deleted itself nicely from the catalog and in all aspects behaved as expected.. The problem was when i tried to delete an instance of it.. I get the error : Error Type: ValueError Error Value: Uncatalog of absent id 'exp/news/HRnews/newsdoc199910101612' - So it evidently cannot uncatalog the newsdoc from the catalog, but should this stop it from deleting the instance ?? I tried manually removing it from the catalog, then deleting it -result : didn't work.. Tried clearing the entire catalog, then deleting - result : didn't work.. Tried indexing all documnets again, then deleting - result : didn't work tried changing the id of the Zclass, to break the documents, so that they would not inherit from zcatalog - result : they didn't break, thus it didn't work .. I'd really like not having to actually delete my Zclass and the recreate it.. Ideas on what i might do wrong ??
