Status: RESOLVED WORKSFORME

(Core :: DOM: Events, defect, P4)

Description

[Klaus]

From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.1b) Gecko/20020722
BuildID:    2002072204

In the page at http://glashoff.net/bugzilla/testempty.html the browser hangs
after clicking on the text in the top of the page.

Reproducible: Always
Steps to Reproduce:
1.Load the page at http://glashoff.net/bugzilla/testempty.html
2.Click on the text at the top of the page.


Actual Results:  The browser hangs which can be recognized by trying the
MOUSEOVER - effect on the text at the bottom of the page which has just been
added for that purpose.

Expected Results:  Mozilla should have worked as usual, .f.i. the mouseover -
effect described above should work on the text on the bottom.

The problem is the following command:
					document.getElementById('t1').firstChild.nodeValue=''

where there is "nothing" or space as value.

This problem is not present in the WINDOWS-Version.

http://glashoff.net/bugzilla/testempty.html gives me a 404. What is the correct URL?

Comment 2

[Olav Vitters]

URL works now.

Browser doesn't completely hang, but selecting text on the page becomes
impossible and the mouseover/mouseout isn't executed anymore. Also, after
clicking in the URL bar, you cannot focus the page (when you clicking on the
page, the URL bar is still selected).
After a reload text selecting, mouseover/mouseout and focus switching work again.

Confirming

See it too (2002080419, WinNT). Problem disappears when you remove #t1
selector's "position:absolute".

-> normal

Marking platform/os -> all per comment 3.

Comment 6

[Vladimir Ermakov]

The hang is not freesing the browser, only events fired at the particular page,
you can still navigate to a different page, or have this one reloaded. Why would
making a node empty during an event block other events from firing... I tried to
remove child instead of setting value to '', and this did not cause any
problems, so it appears the only time this occurs is if value is set to ''.
