I have a ZCatalog which contains about 850k entries. Each entry is a zclass instance which is NOT 'catalog aware' (ie. catalog_object was used to explicitly add the record to the zcatalog). The records exist in the zcatalog and I can access a single record's data_record_id_ by: <dtml-call "REQUEST.set('recid', '1049298593')"> <dtml-in "Catalog({'master_recid' : recid})"> <dtml-call "REQUEST.set('drid', data_record_id_)"> </dtml-in> drid= <dtml-var drid> Displays: drid= 17223047659 All is well, so far... I now want to remove the record from the ZCatalog: <dtml-call "Catalog.uncatalog_object(recid)"> generates the following error in my log file: 2004-07-02T11:13:07 ERROR(200) Catalog uncatalogObject unsuccessfully attempted to uncatalog an object with a uid of 1049298593. and <dtml-call "Catalog.uncatalog_object(drid)"> generates the following error in my log file: 2004-07-02T11:21:07 ERROR(200) Catalog uncatalogObject unsuccessfully attempted to uncatalog an object with a uid of 1722304759. So, how do you remove a 'non-catalog aware' object from a zcatalog? (this is the first time I have used non-catalog aware instances, in previous projects I used catalog-aware objects and just deleted the object in the folder and the object was automatically removed from the zcatalog). Thanks for any ideas! Jonathan
