Hi, I have created an object in the ZODB that I cannot see in the ZMI and now don't know how to remove it. More importantly I would like to understand what I did so as not to do it again. I am sure more info is needed to track down the problem but I don't know what it would be. A brief explanation of what I am trying to accomplish. I am creating a folderish object with its id be autogenerated. Inside of this new object I want to create another folderish object with an id = 'Invoices'. Here is the 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 Products.PRealEstate.PRealEstate, line 253, in addPParcel Module OFS.ObjectManager, line 272, in _setObject Module Products.PRealEstate.PParcel, line 139, in manage_afterAdd Module OFS.Folder, line 46, in manage_addFolder Module OFS.ObjectManager, line 244, in _setObject Module OFS.ObjectManager, line 77, in checkValidId Bad Request: The id "Invoices" is invalid--it is already in use. Here is the code that caused it: def manage_afterAdd(self, item, container): """ Processing after creation """ item.manage_addProduct['OFSP'].manage_addFolder('Invoices', '') Thanks, Mike
