I have a method that is returning an error that I have not been able to resolve. I have tried to duplicate the error in python to no avail. I am sure the solution is very simple I just don't see it. tia, Mike Here is the method: 172 def listEntriesByGroup(self, groups=["All"]): 173 "Method to list Entries" 174 ret=[] 175 if type(groups) != ListType: 176 EntryIDs = [groups] 177 if groups == "All": 178 for entry in self.Entries.values(): 179 ret.append(entry) 180 else: 181 for entry in self.Entries.values(): 182 if entry.Group in groups: 183 ret.append(entry) 184 return ret The traceback is: 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.dlAddressBook.AddressBook, line 134, in index_html Module Shared.DC.Scripts.Bindings, line 252, in __call__ Module Shared.DC.Scripts.Bindings, line 283, in _bindAndExec Module Products.PageTemplates.PageTemplateFile, line 96, in _exec Module Products.PageTemplates.PageTemplate, line 95, in pt_render - <PageTemplateFile at /TEST/test/> Module TAL.TALInterpreter, line 186, in __call__ Module TAL.TALInterpreter, line 230, in interpret Module TAL.TALInterpreter, line 689, in do_useMacro Module TAL.TALInterpreter, line 230, in interpret Module TAL.TALInterpreter, line 712, in do_defineSlot Module TAL.TALInterpreter, line 230, in interpret Module TAL.TALInterpreter, line 578, in do_insertStructure_tal Module Products.PageTemplates.TALES, line 217, in evaluate - URL: main_page - Line 14, Column 16 - Expression: standard:'here/content' - Names: {'container': <AddressBook at /TEST/test>, 'default': <Products.PageTemplates.TALES.Default instance at 0x868e42c>, 'here': <AddressBook at /TEST/test>, 'loop': <SafeMapping instance at 84c75e0>, 'modules': <Products.PageTemplates.ZRPythonExpr._SecureModuleImporter instance at 0x86b2b7c>, 'nothing': None, 'options': {'args': (<AddressBook at /TEST/test>, <HTTPRequest, URL=http://zeus:8080/TEST/test/index_html>)}, 'repeat': <SafeMapping instance at 84c75e0>, 'request': <HTTPRequest, URL=http://zeus:8080/TEST/test/index_html>, 'root': <Application instance at 9643db0>, 'template': <PageTemplateFile at /TEST/test/>, 'traverse_subpath': [], 'user': admin} Module Products.PageTemplates.Expressions, line 206, in __call__ Module Products.PageTemplates.Expressions, line 201, in _eval Module Products.PageTemplates.Expressions, line 100, in render Module Products.PageTemplates.ZRPythonExpr, line 74, in call_with_ns Module Shared.DC.Scripts.Bindings, line 266, in __render_with_namespace__ Module Shared.DC.Scripts.Bindings, line 283, in _bindAndExec Module Products.PageTemplates.PageTemplateFile, line 96, in _exec Module Products.PageTemplates.PageTemplate, line 95, in pt_render - <PageTemplateFile at /TEST/test/> Module TAL.TALInterpreter, line 186, in __call__ Module TAL.TALInterpreter, line 230, in interpret Module TAL.TALInterpreter, line 459, in do_setLocal_tal Module Products.PageTemplates.TALES, line 217, in evaluate - URL: indexAddressBook - Line 1, Column 0 - Expression: <PythonExpr here.listEntriesByGroup(SelectedGroup)> - Names: {'container': <AddressBook at /TEST/test>, 'default': <Products.PageTemplates.TALES.Default instance at 0x868e42c>, 'here': <AddressBook at /TEST/test>, 'loop': <SafeMapping instance at 90ae240>, 'modules': <Products.PageTemplates.ZRPythonExpr._SecureModuleImporter instance at 0x86b2b7c>, 'nothing': None, 'options': {'args': ()}, 'repeat': <SafeMapping instance at 90ae240>, 'request': <HTTPRequest, URL=http://zeus:8080/TEST/test/index_html>, 'root': <Application instance at 9643db0>, 'template': <PageTemplateFile at /TEST/test/>, 'traverse_subpath': [], 'user': admin} Module Products.PageTemplates.ZRPythonExpr, line 48, in __call__ - __traceback_info__: here.listEntriesByGroup(SelectedGroup) Module Python expression "here.listEntriesByGroup(SelectedGroup)", line 2, in f Module Products.dlAddressBook.AddressBook, line 182, in listEntriesByGroup TypeError: 'in <string>' requires character as left operand
