292030 - Moving messages to another folder results in unexpected mail thread sorting

Status: RESOLVED EXPIRED

(Thunderbird :: Mail Window Front End, defect)

It appears that mail threads are sorted based on the last-modified date of the
message.  This means that when you move some messages from one folder (e.g.
inbox) to another, you get unexpected sorting of mail threads... it will be
sorted by the modified-date of the 'root' message of the thread, which
essentially means you end up with the threads sorted by the order you moved them
into that folder.  I would expect to continue to see the threads sorted by the
received date of the 'root' message of each thread.

(Does that make sense?)

Reproducible: Always

Steps to Reproduce:
1. Select the messages in a thread in your inbox and drag them to another folder.
2. Select the messages in an *earlier* thread in your inbox and drag them to
that folder.
3. Look at the folder.  The second thread is displayed after the first thread
(e.g. in the opposite order they were in the inbox).
Actual Results:  
See steps.

Expected Results:  
Keep the threads in the same order they were in the inbox, e.g. by default sort
by  'received' date of each thread's 'root' message.

Have you actually set the sort order for the folder to "by date"?

The date of the messages is not modified.  The default sort order for a folder 
is "by order received".

xref bug 283874.

What do you mean by "set sort order for folder to 'by date'"?  I looked at the
other bug (which I don't think is quite the same) and added the line about
mailnews.thread_pane_column_unthreads to my prefs.js and it didn't seem to have
any effect on this problem.

Note that message threads work as I expect in my inbox.  It's when I move
messages to another folder that the message threads are not sorted in correct
date order.  Is there any chance this is because I use IMAP and my folders are
on the server?

In any event,

This is an automated message, with ID "auto-resolve01".

This bug has had no comments for a long time. Statistically, we have found that
bug reports that have not been confirmed by a second user after three months are
highly unlikely to be the source of a fix to the code.

While your input is very important to us, our resources are limited and so we
are asking for your help in focussing our efforts. If you can still reproduce
this problem in the latest version of the product (see below for how to obtain a
copy) or, for feature requests, if it's not present in the latest version and
you still believe we should implement it, please visit the URL of this bug
(given at the top of this mail) and add a comment to that effect, giving more
reproduction information if you have it.

If it is not a problem any longer, you need take no action. If this bug is not
changed in any way in the next two weeks, it will be automatically resolved.
Thank you for your help in this matter.
