I have patched my horde-webmail-1.2.1 installation with your changes, 
and it works perfectly.



Thanks a lot.

Fixed in IMP 4.3.3 (backported some changes that were made to the 
eltDiff code in imp/lib/IMAP/Tree.php in IMP 5).

Hi,

A little feedback : I have the same behaviour with horde-webmail-1.2.1

The "patch" still works with the 3 web browsers mentioned.

Installation infos : horde-webmail-1.2 ; php-5.2.6 ; debian etch

I initially had this problem with the packaged imp-4.3, but it still 
remains with imp-4.3.2

Tested web browsers : Mozilla firefox 2.0.0.18, IE7, Safari 3.2 for 
windows (all on OS windows XP SP3)



By Dimp interface, after the renaming of a new folder, the folders 
tree is partially updated dynamically.



For instance, I try to rename the folder "foo" in "bar" :

- I get the message 'The folder "foo" was successfully renamed to "bar"'.

- The folder "bar" appears successfully in the folders tree.

But :

- The folder "foo" doesn't disappear from the folders tree.



Setting the javascript debugging and using dimp/js/src doesn't produce 
any alert.



Refreshing the page doesn't produce any change.

I need to disconnect-reconnect to see the correct folders tree without 
the folder "foo".





I have tried to understand  and it might be due to the use of the 
function _getList before the deletion of the folder "foo".

It sets the static variable $full_list with the folder "foo" and 
caches it even after its correct deletion.

So, this folder is finally maintained and does not make part of the 
deleted folders in the getFolderResponse result.



I have followed a part of the calls (I get the same in imp-4.3 and imp-4.3.2).

If I am not mistaking, a part of the calls is :

with Folder as horde/imp/lib/Folder.php, Search as 
horde/imp/lib/Search.php, Tree as horde/imp/lib/IMAP/Tree.php

- Previous calls to folderList set $full_list with the folder "foo"

Folder.rename calls

   Folder._onDelete which calls

     Search.sessionSetup(true) which calls

       Search.createVINBOXFolder which calls

         Tree.getPollList which calls

           Tree.folderList which calls

             Tree.showUnsubscribed which calls

               Tree._getList which returns by the 1st return 
instruction with $full_list already set



I have put aside the use of $full_list to make the Tree._getList 
function returns by the 3rd return instruction.



I have modified horde/imp/lib/IMAP/Tree.php (v 1.25.2.60 and v 
1.25.2.64), please see attached patch dimp_renamefolder.patch.

It can be applied on these two versions of the Tree.php.



Renaming a folder reacts dynamically and successfully :

- I get the message 'The folder "foo" was successfully renamed to "bar"'.

- The folder "foo" smoothly disappears from the folders tree.

- The folder "bar" appears in the folders tree.

It seems to work (maybe a border side effect waiting in the dark) on 
the three web browsers mentioed above.



Thanks for reading and help.
