I am trying to pack a DBTab mounted database via an external method. I have two separate db's mounted (Data.fs, MyDB.fs) and only want to pack MyDB.fs I have tried: self.Control_Panel.Database.MyDB.manage_pack() with no luck, it generates the following error: Error Type: AttributeError Error Value: MyDB Error Traceback: Traceback (innermost last): Module ZPublisher.Publish, line 98, in publish Module ZPublisher.mapply, line 88, in mapply Module ZPublisher.Publish, line 39, in call_object Module OFS.DTMLMethod, line 126, in __call__ Module DocumentTemplate.DT_String, line 474, in __call__ Module Products.ExternalMethod.ExternalMethod, line 231, in __call__ __traceback_info__: ((), {}, None) Module /apps/zope/Extensions/jhtmp.py, line 8, in jhtmp AttributeError: MyDB I have looked at the source for the 'pack' button (in Control_Panel/Database/MyDB) but found no clues (the form just calls 'manage_pack' directly with no reference to which database should be packed. I have also looked at the source for manage_pack and found no clues. Somebody must have done this! Thanks, Jonathan
