Status: RESOLVED DUPLICATE of bug 393579

(Thunderbird :: Mail Window Front End, defect)

Description

[Jürgen 'JiHa' Harter]

+++ This bug was initially created as a clone of Bug #393579 +++

User-Agent:       Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9a8pre) Gecko/2007082317 Mnenhy/0.7.5.20003 SeaMonkey/2.0a1pre
Build Identifier: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9a8pre) Gecko/2007082317 SeaMonkey/2.0a1pre

Using the twisty at the Subject:-field at the headerpane to collapse and reopening it again makes the twisty in front of the To:-field disappearing.

Reproducible: Always

Steps to Reproduce:
1. You need a message with many email recipients in the To: so there is a twisty present in front of the To: at the headerpane.
2. Switch to collapsed view by clicking the twisty in front of the Subject:-field at the headerpane. 
3. Switch to the detailed view again by clicking the twisty in front of the Subject:-field again.
Actual Results:  
The twisty in front of the To:-field is gone.

Expected Results:  
The twisty in front of the To:-field should be still present as it was.

If the headerpane is already collapsed at the startup, the twisty at the To:-field will be shown the first time when reopening the headerpane. Collapsing and reopening again will kill the twisty.


I tested without mnenhy (!) with:
-- Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9a8pre) Gecko/2007082317 SeaMonkey/2.0a1pre (self compiled from cvs) -> Twisty killed
-- 2007082405_thunderbird-2.0.0.7pre.en-US.linux-i686 (official trunk nightly) -> Twisty *not* killed
-- 2007082403_thunderbird-3.0a1pre.en-US.linux-i686 (official trunk nightly) -> Twisty killed
-- TB version 1.5.0.12 (20060911) (official SUSE version)  -> Twisty *not* killed

I enabled Mnenhy in the official SUSE TB version 1.5.0.12 (20060911) from above and the twisty *gets* killed.

I guess all this has something to do with Bug 62033 which brought the feature of references links to the headerpane. Mnenhy also does this.

Duping, since it turned out to be in a shared binding.
