65561 - Lots of spaces being added to my document when editing

Status: VERIFIED FIXED

(Core :: DOM: Editor, defect, P1)

Description

[scottputterman]

I created my status report using the 2001011204 NT build.  Everything seemed fine.
After shutting down and starting up again, I had to edit the document. When I
started inserting characters or deleting characters in individual items of a
bullet list, large numbers of spaces started getting added to my lines.  For
example, if I had:

"This is a test"

and I started typing after test, it would suddenly change the line to something
like:

"This     is a test of this bug"

I don't see any obvious pattern.

nominating for nsbeta1 because it's hard to edit a document when I have to go
back and delete all of these new spaces.

joe I suspect this is a dup of one of your bugs

I will attach a sample file for this.  In the file I'm going to attach, look at
the 2nd bullet that starts with "David".  In the very last sentence, look for
"And he did some performance".  Put the cursor right before the 'p' in
performance. Then type "test".  You will see bug 65615 as well, but notice that
extra spaces get added to the rest of the bullet.

Joe--is this a duplicate of bug #43033?

Here are the steps for reproducing this bug (from bug #69079 by shrir):

1 Open Composer
2 Add a few items to a bulleted list
3 Keep the last item blank (do not enter any text and just leave the bullet   
there)
4 Save the File and Reopen in Composer
5 Now, click with mouse in the last (empty) bullet item
6 Press the BACKSPACE key on keyboard (expecting that the bullet item gets   
deleted and cursor goes to the earlier item's last character)
7 Observe that as soon as you hit Backspace, the last item shifts down by a line 
and cursor stays there. Pressing Backspace again brings the last item back to 
where it was and moves the caret to the last-but-one item's first character.

pushing off ws work to moz0.9.1 since it is not ready for prime time.
Interested parties should check out bug 65557, which has the patches.  We are
getting pretty close here.

pulling back some bugs which may be fixed by the whitespace work.

Oh God ! This is showing something different now (0514 trunk on windoz). I used 
kathy's testcase(2001-02-19 08:43). What I see is..after step6 , hitting 
backspace once does nothing..hitting it again does nothing..then hitting 
backspace the third time moves the caret to the earlier item (keeping the last 
item intact). The fireball of death is rolling back again :) . reopening

Ok, removing whitespace from status.  I think this is something else (just a bug
in the deletion code).  Setting to 092 for now.  Might get pulled back.

This bug report has degraded.  The original bug reported is definitely fixed.  We 
need to close this and open a new bug on the seperate issue.  I filed 80880 on 
the new bug and am closing out this bug.

Joe filed a new bug for the other problem.
