536054 - Wrong error message for saving drafts - cites Sent folder instead of Drafts

Status: RESOLVED DUPLICATE of bug 257735

(Thunderbird :: Message Compose Window, defect)

Description

[Erich N. Pekarek]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; de; rv:1.9.1.6) Gecko/20091201 Firefox/3.5.6 (.NET CLR 3.5.30729)
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; de; rv:1.9.1.5) Gecko/20091204 Thunderbird/3.0

When saving a mail to an IMAP drafts folder, the german localized build of Thunderbird complains about not beeing able to save to the "Gesendet" (Sent) folder: 
"Nachricht konnte nicht in den Ordner "Gesendet" kopiert werden. Nochmals versuchen?"

 Sent? -> Drafts!

The folder settings are on their defaults - so thunderbird would determine the right drafts folder automatically. (The error first occured with update from 2.0.0.27 to 3.0)



Reproducible: Didn't try

Steps to Reproduce:
1. open a new mail for writing
2. save to drafts
Actual Results:  
Error message appears (Error not yet reproduced), but this ticket is for the wrong translation stating "sent folder" instead of "drafts folder".

Expected Results:  
Error: "Nachricht konnte nicht in den Ordner "Entwürfe" kopiert werden. Nochmals versuchen?"

Since update from 2.x to 3.0.
Reason for error itself unknown - just reporting the wrong translation.

The original en-US String is:
"There was an error copying the message to the Sent folder. Retry?"

See in:
http://mxr.mozilla.org/comm-central/search?string=12571=&find=/en-US

So this is no l10n error.

Erich, (correction) dup of bug 354064?

No, I don't think so. The error message may be the same, but the error occurs for other reasons.

As far as I could observe it, it appears on Windows (32 bit) and linux (32 bit) (64 not tested yet) and is related to a common user behavior:

User closes Thunderbird's main window, while a compose window is still open.
It seems, the IMAP session expires after a while and does not get reinitiated by clicking the "send" button from within the compose window.

Hence the IMAP connection will be down, saving to either drafts or sent won't work, while the message itself is being sent via SMTP without problems.

Since unexperienced users do this quite often, I suggest it's worth fixing it.

Solutions may include:
* Embedding compose window in a tab.
* Let compose cache the (actual) IMAP session's credentials.
* Let compose instantiate a new connection by asking for the (IMAP) credentials.
* Let compose -"- by reusing the stored (IMAP) credentials.
* Block closing of the main instance while compose windows are still open.
