Currently we don't handle the filepicker's GetFolder mode correctly.  In

1) we assume there is a filter list.  this is wrong, and causes a crash trying
to save all attachments in mail.

2) we don't even want to show the filter list in GetFolder mode

3) only folders should be shown in this mode.

I have a patch that addresses these problems.

Nominating for RTM based on the fact that this causes a 100% reproduceable crash
on a fairly accessible (and useful!) operation.

the patch i just attached is somewhat cleaner and also addresses the fact that
if no folder is selected, the current directory should be used.

Ok, apparently there IS a problem if you try to select a directory via changing
TO that directory and hitting OK.  Selecting the directory from the list (in the
parent directory) works fine for me.  Changing to the target directory and
hitting OK results in nothing happening.  Are you still seeing the crash, or
just this problem where the OK button doesn't work?

This bug has re-opened.  Clearly the patch that was approved did not heal the
problem.  Pushing the status back to rtm-need-info, and removing "fix in hand"
comment, and patch keyword.
Please update with status, and nominate if you have a safe reviewed fix.

Best case resolution for this may be just simple bulletproofing that stops the
crash, if one still exists.  If the only problem is that the OK button is active
when there is no directory selected, then please minus and future this bug.

I don't believe there is still a crash, at least I can't reproduce one.  I'm
waiting for jefft to tell me whether he is seeing a crash or not, and how to
reproduce it. Neither jag or I can make this crash in today's builds.

The problem I *am* seeing, is that if you try to select a folder for the saved
attachments by changing TO that directory (as opposed to clicking on the folder
from the level above and then clicking OK), the filepicker will not go away.
This all boils down to the fact that we weren't clearing the filename textfield
on the directory change, so the name of the folder that you changed into is
still there.  For example:

- Suppose I have a directory under my home directory for saved attachments,
/home/bryner/attachments.  When the filepicker comes up, it will start in
- If I select the attachments directory by clicking once on it in the file list
and clicking OK, everything is fine.
- But, if I double-click the attachments directory to change to that directory,
the textfield will still contain the text "attachments" (since clicking on a
file puts its name in the textfield), so clicking OK will try to save in
/home/bryner/attachments/attachments, which does not exist, and the filepicker
doesn't exit because you haven't selected something valid.  Can  be worked
around by manually clearing the textfield.  Note that this problem ONLY
manifests itself in the "Select Folder" mode of the filepicker, which is
currently only used, to my knowledge, in Save All Attachments.

There is an easy, 1-line fix for this to make sure we clear the textfield on
chdir.  If you think this fix is worth it, we can do a trial checkin on the
trunk (after proper reviews and testing), otherwise, ->Future (assuming there is
no crash scenario).

No, it is too late for such minor improvements.  Typical case will be to select
directory while it is selected.  If that is the only problem, then this will
turn into rtm-/future.

The biggest problem I am having with my test is I cannot pick any directory at 
all. The drop down directory list is empty. Click on ".." button does nothing. 
Then click on the "Cancel" button it crashed out with the following error 
messages. Adding myself to the cc list. (I am testing with my daily branch daily 

can't get parent directory

That sounds EXACTLY like what I fixed a couple of weeks ago.  Are you sure you
don't have other mods in your tree?  Can you try today's branch build from sweetlou?

Comment 26

I did a grep on my cvsco.log and cvsco-ns.log and I don't have any local 
modifications. I'll try the release build from sweetlou next.

The release build does fix the problem. I am puzzled now how come my branch 
build doesn't. marking the bug fixed.
