11010 - when I remove the last option element of a HTML select object, the text stays behind.

Status: VERIFIED FIXED

(Core :: DOM: Core & HTML, defect, P3)

Description

[(not reading, please use [e-mail] instead)]

in the message compose window, we are using a html select widget to list the
attachments.

in the menu, we have a "remove last attachment".

if my select widget has 3 options, removing #3 works as expected:  two are left.
when I have 2 and remove the last 1, it works also.

when I remove 1 when I have 1, it works, but it "looks" like one is still left,
as the text of the last option element stays behind.

my current work around is, when I remove the last one, add a blank option, with
text = " ", and then remove it.

A quick test and I didn't see any problems. I will investigate further.

this test case exhibits the bug on Linux with today's build (8/2/99)
after I hit the "Remove all" button, the three options are gone, but the text
for the first option, "1st" still remains.

I'm not seeing problem anymore in my build (9-7-99) on linux.

I've removed my work around from
mozilla/mailnews/compose/resources/content/MsgComposeCommands.js

marking this as fixed.

This bug needs to be reopened.

I am seeing this in 2002060808-trunk Win98 build.  I don't know how long it has
been around, since I just started tickling this bug with a new application.

The given test case fails.  Also, removing all nodes using DOM manipulation ala:

while (SelectNode.hasChildren())
    SelectNode.removeChild(SelectNode.lastChild);

fails the same way.
