393400 - Adding an attachment to a draft does not trigger unsaved changes dialog

Status: RESOLVED DUPLICATE of bug 374195

(Thunderbird :: Message Compose Window, defect)

Description

[Jon B]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.6) Gecko/20070725 Firefox/2.0.0.6
Build Identifier: version 2.0.0.6 (20070728)

On Close, unsaved changes to the body, header, or recipient fields trigger the unsaved changes dialog, but changes to the attachment field do not.

Reproducible: Always

Steps to Reproduce:
1.Compose a message
2.Type something in the body
3.Press Save
4.Type something else
5.Press Close

Since this version is different from the saved version, the unsaved changes dialog will pop up:

"Message has not been sent.  Do you want to save the message in the drafts folder?"

6.Press Cancel
7.Press Save to update the saved version

Now if you press Close, it will not ask you to save, since this version has already been saved.

8.Now, add an attachment
9.Press Close
Actual Results:  
Although the mail has been changed (by the addition of an attachment), it does not prompt you with the unsaved changes dialog.  If you look in the drafts folder, the saved draft has no attachment.

Expected Results:  
After adding an attachment and pressing Close, the unsaved changes dialog should pop up as if a change had been made to the body of the document.
