Textarea changes vanishing... my bad, or is IE evil?
Sorry for borderline-off-topic posting, but I'd like to see if anyone else in zope-land is observing this behavior... Some of my zope users have been complaining recently that their edits mysteriously vanish. Today we came up with a consistently reproducible case: 1. go to any page template... let's call it my_template 2. make some changes and submit 3. navigate to somewhere else 4. navigate back to my_template's edit form (not using the back button, but i don't know if that matters). Now the textarea shows the text as it was at step 1, when it should show the text as it was after step 2. At this point, if you hit refresh, your changes from step 2 show up and all is good. But if you forget to do so, you'll be editing stale text and wiping out the work you did in step 2. Changing the Internet Options settings does not help... we've all got it set to check for new versions every time. The reason I am suspicious of IE is that I cannot reproduce the bad behavior with any mozilla-based browser that I've tried (firefox/linux, mozilla 1.5/linux, netscape 7.1 / w2k). We've only seen this for a few weeks so I'm wondering if it could be part of a windows update IE fix. But the really maddenign thing is that now I can't reproduce the behavior on a fresh zope 2.7.0 instance. Sigh... maybe I just have some bad AcceleratedHTTPCacheManager settings somewhere but I really can't find anything suspicious so far. Any other ideas, anyone? -- Paul Winkler http://www.slinkp.com
If you are using something like apache in front of zope is it possible that the page is being served up from the 'apache' cache? If you think the problem is with the browser have you embedded the html meta tags in the form that cause the browser to expire the page immediately (this works for us and we use IE). Alternatively, someone in this list mentioned that they had better luck 'expiring' pages by setting the header parameters directly instead of the html meta tags.

I do not see this behaviour with Konqueror... -- Dieter

I believe I've seen this behaviour with some recent versions of Mozilla-derived browsers. Damned annoying too. The most recent firefox for Linux doesn't exhibit this behaviour, IIRC.

Interesting. I've only been able to provoke it with IE, not with a fresh Zope instance, and not with any Mozilla-derived browser. I got rid of a ton of inappropriate cache manager associations and I *think* it's gone now. -- Paul Winkler http://www.slinkp.com
