Searching for a variable from ZPT.
by Jason Leach 24 Sep '04

Is their an easy way to search for a var in REQUEST? In my ZPT I have a look in REQUEST.SESSION, options and REQUEST.form for a var; it can get passed in several ways depending on what calls the ZPT. I would like one clean way. Not three conditions in my ZPT. Any ideas?

I find that hard to believe in Zope 2.7.2. Can you post an example traceback? cheers, Chris -- Simplistix - Content Management, Zope & Python Consulting - http://www.simplistix.co.uk

reloading a pop-up box
by Laura McCord 24 Sep '04

24 Sep '04

This is probably outside the scope of this discussion forum but perhaps someone has some experience with this. I have a dhtml pop-up box that contains a form that calls a dtml method that calls a python script. I notice that I can't seem to reload only the content within the pop-up box. I have been using this <dtml-call expr="RESPONSE.redirect(URL1 + '/index_html')"> but would rather reload the box and not the whole page. Any ideas?

ExternalEditor has a mind of its own
by nwingfield＠dixon-hughes.com 24 Sep '04

24 Sep '04

I have just installed ExternalEditor on my Win XP Pro system, and it seems to be ignoring the settings in my ZopeEdit.ini file. Instead, it insists on opening Python Scripts in IDLE (not the registered application for .py files on my system) and Page Templates in Microsoft Word (again, not the registered application for .html files on my system), and setting WebDAV locks even though I explicitly disabled this behavior. Does anyone know what is going on? ID:[{20040924151544.8286.9730247602-12.6.18.86}]

preventing transaction rollback
by Sean Hastings 24 Sep '04

24 Sep '04

I have a section of code that I want to have run only once during a request. It mails out some information about the request. I want only one email per request even if a conflict occurs during the request. I am having no luck eliminating duplicate emails. I have tried this a few different ways now, but currently my code looks something like this: def theFunction(self,REQUEST): "docstring" ...do some stuff... get_transaction().commit() try: ...send the email... get_transaction().commit() except: pass ...do some more stuff... return self.return_page_template(REQUEST) I thought that this try block with a commit() would isolate the send mail code in its own transaction, and then catch any conflict exception and ignore it. But I am still getting multiple emails per transaction when multiple requests happen at the same time and conflicts occur. How can I isolate a part of the code so that it can never roll back and execute again? --Sean

Zope Session Timeout
by Asad Habib 24 Sep '04

24 Sep '04

Does anyone know how to check if a Zope Session has timed out? I know that this value is set in the Session Data Container object that resides in the Temp folder at the root level. But how can I check to see if this time limit has been exceeded? I would like to redirect the user to a customized error page when this happens. Any help would be greatly appreciated. Thanks. - Asad

Mysterious Zope Run-time Error
by Asad Habib 24 Sep '04

24 Sep '04

I have a variable called 'currentSessionError' that I have placed in the SESSION attribute of the REQUEST object. I am having a problem making the value of this variable persist when I run Zope with SSL. In particular, the value of this variable does not persist when I access a form(i.e. DTML document) from a second form via a standard hypertext link. The value of this variable clearly exists when the second form is being processed but upon accessing the link, the value of this variable is reset to None. I have ascertained this by using <dtml-var "REQUEST.SESSION.get('currentSessionError')"> in both forms. This is the only SESSION variable whose value does not persist when I run Zope with SSL. I have numerous other variables in the SESSION that work as expected. Also, when I run Zope without SSL, the value of this variable persists between the two forms. Has anyone come across a similar problem? Any help would be greatly appreciated. Thanks. - Asad

Zope 2.7 Problems
by Ralph van den Houdt 24 Sep '04

24 Sep '04

Hi All, A while ago I started using Zope 2.7 instead of Zope 2.6. After this upgrade thing are not running as expected. Currently using Zope 2.7.2 Problem 1) Zope crashes spontaniously After running for a while the zope server stops responding. When I check the server the main zope thread is killed and the subthreads are running on there own without the parent proces. Problem 2) Zope leaks memory After installing zope 2.7 it looks like the server leaks a lot of memory. The memory keeps adding until the server runs out of memory. Does anyone know a solution to these problems. Greetings Ralph
