Thanks Andy for your help on this - the problem was in the registry. There was another registry setting ..\Services\<servicename>\Parameters\Start that was not being set by the installation process (the Start parameter had retained the default directory information for python.exe). I re-installed Zope using the default settings and everything works ok.

objectValues return value
by David Bear 05 Dec '02

05 Dec '02

I wrote a script the returns a list object of all title_or_id values of objects in a folder. The problem is when there are no objects in the folder. The script should return a list contianing the string 'none'.. but doesn't. In fact, the script seems to either hang or have no return value... Any pointers? # returns a python list contained the title of the page templates in this folder list = context.objectValues('Page Template') if list == None: return ['none'] newlist = [] for zpt in list: newlist.append(zpt.title_or_id()) return newlist -- David Bear College of Public Programs/ASU Mail Code 0803

Thanks Dieter, I have two DA instances defined for testing and had not updated one of the methods to use the correct one. Now all is well.

Problem running Zope on Windows 2000
by Jerry Leeson 04 Dec '02

04 Dec '02

I have installed Zope 2.6 in a Windows 2000 environment and the Zope service will not work. In the event log I get the following error: The instance's SvcRun() method failed File "C:\INETPUB\wwwroot\TESTZOPE\bin\lib\win32\lib\win32serviceutil.py", line 601, in SvcRun self.SvcDoRun() File "C:\INETPUB\wwwroot\TESTZOPE\ZServer\ZService.py", line 181, in SvcDoRun self.start_zserver() File "C:\INETPUB\wwwroot\TESTZOPE\ZServer\ZService.py", line 203, in start_zserver None, None, 0, 0, None, None, win32process.STARTUPINFO()) pywintypes.api_error: (3, 'CreateProcess', 'The system cannot find the path specified.') Is there some sort of path setting that is not being set during the install? Alternatively, I could try to use IIS or Apache webserver but the administration guide does not seem to be available yet to tell me how to do so. Any ideas would be greatly appreciated.

I'm wondering what folks are using/recommending for managing membership on a Zope/CMF/Plone site. I don't have any sort of external membership sources to deal with. thanks, Danny

ZClass inheritancs:propertysheets
by Patrick Stinson 04 Dec '02

04 Dec '02

Am I now corrent in assuming that ZClasses do NOT inherit property fields from their super-ZClasses? if not, how do you access the inherited propertysheets, instead of the actual property sheets.

The following is a python constructor that I usually use.

I have a product 'Lucy' which has folderish ZClasses 'bob' and 'bill' in it. Each instance of a bob should be constructed with a bill named 'Willliam' in it. The default DTML method bob_add has the following snippet: <dtml-with "bob.createInObjectManager(REQUEST['id'], REQUEST)"> <dtml-comment> ... </dtml-comment> </dtml-with> Where and how do I construct the bill ? My naive thought was to put a <dtml-call "bill_add(id='William')"> in the dtml-with statement, but that doesn't seem to work. Suggestions? I've read 'The Zope Book' a couple times, looked through ZopeLabs and didn't see anything like this except for adding a folder, which isn't that helpful because they're a standard class and have various management methods defined for them. Ideas? J.

Unexpected script behavior
by Michael Long 04 Dec '02

04 Dec '02

I am getting unexpected results from my python script. Here is a snippet form the python script: container.DeletePerson_sql(PersonId=PersonId) --[ZSQL Method] ClearPersonDetails() --[Python function] PersonList = container.GetPersonList_sql() --[ZSQL Method] request.set('PersonList', PersonList) return container.ContactTemplate() --[ZPT] After the person is successfully deleted from the database another call to the database is made to get a list of people and set that to 'PersonList'. This variable is then used to render the page. The problem is that the deleted person still shows up in the rendered page. When the page is called a second time the correct data is shown. I have validated that the data is deleted from the database when expected. Why would the 'PersonList' not have the correct data? Thanks, Mike

tracebacks vanished
by Tom Cameron 04 Dec '02

04 Dec '02

I have upgraded to 2.6 on redhat and now I cant seem to get tracebacks to display. I managed to get the EVENT_LOG_FILE working. but it makes no difference if I use the -D frag on the z2.py file or not. In both cases I no longer see any tracebacks of errors. Any hints appreciated. Thanks Tom
