Hello everyone, again I'm stuck :-( I have a python script that looks as follows: results=[] for ids in context.objectIds('Folder'): results.append(ids) newid = str(int(max(results)) + 1) context.manage_addProduct['OFSP'].manage_addFolder(newid, title="person") newaddr=getattr(context, newid) newaddr.manage_addProperty("test", "test", string) return 0 When I run it it returns the error: Error Type: TypeError Error Value: can't pickle module objects It looks like as if the Folder doesn't get created when the manage_addProperty() function tries to modify it. If I comment out the line with the manage_addProperty() function the folder however gets created and newaddr has as sensible value. Please help me to clarify this. Thanks in advance Roman
