[Moin-user] User Says Page Edits Are Not Always Saved

Thu Jun 28 16:40:49 EDT 2007

One thought I had was that my user was hitting the Cancel button
instead of the Submit button.  A closer inspection of the log data
indicates she hit the Submit button.

If I edit a wiki page, update it, and save it; and then edit the page
and hit cancel, the difference in the response length to the two POSTs
is 49 bytes.  This is the difference between the length of the two
status messages:

 Edit was cancelled.
 Thank you for your changes. Your attention to detail is appreciated.

If I then edit the page and click Save without changing anything, the
difference in the response length is 21 bytes, which is the difference
between the length of the messages:

 You did not change the page content, not saved!
 Thank you for your changes. Your attention to detail is appreciated.

Matching the Apache log against the wiki page info timestamps shows 4
of the POSTs that did not update the wiki page had a response length
difference of 21 bytes, indicating moin said the page was not changed. 
To confuse things a bit, there was a 5th instance of a POST without a
wiki page update that had a difference of 20 bytes, and a 6th with a
difference of 19 bytes.

Googling for some IE related issues, I found some interesting comments
about updating textareas with only use of paste rather than keying. 
But the instances I found all seemed to include other special
circumstances.

Up to last night, my system was Moin 1.5.6 (now 1.5.8), Apache with
mod_python on Fedora Core 6.  My user is remote to the server and is
running IE 6 on W/XP.  I don't think my user has SP2 installed.  I know
she sometimes pastes text from MS Word documents.
