120577 - tree doesn't grow scrollbars, and corrupts data

Status: RESOLVED DUPLICATE of bug 59108

(Core :: XUL, defect)

Description

[David Casti]

From Bugzilla Helper:
User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:0.9.7) Gecko/20011221
BuildID:    2001122106

The tree widget does not grow vertical scroll bars when content extends beyond
the end of the window.  Scrolling beyond the window with the keyboard results in
items disappearing from the tree widget.  This basically makes the tree
unusable, although it has features which are not available in the outliner (eg.
the ability to embed input controls).  Que Terrible!

Reproducible: Always
Steps to Reproduce:
1. load the attached XUL code in Mozilla.
2. Click to expand "Cisco"
3. Click to expand both "9000 Family" and "7000 Family"
(note that no scrollbar has appeared)
4. Click to select "Cisco"
5. Press the down-arrow key 6 times
(note that "Cisco" has now disappeared)
6. Press the down-arrow key again
(note that "9000 Family" has now disappeared)
7. Press the up-arrow key until all items have been restored

Expected Results:  1. Scrollbars should have grown at step 3
2. Content should have scrolled at step 5

Looks like the same issue as bug 59108.
I'm not sure if the tree widget is even still being used in Mozilla.
