131843 - javascript onblur event called for checkbox or radio control results in a crash

Status: RESOLVED WORKSFORME

(Core :: DOM: UI Events & Focus Handling, defect)

Description

[Madhur Bhatia]

1. open the attached testcase.
2. tab to the "onblur event" checkbox
3. hit enter
 
the onblur event is triggered. An alert box is displayed saying  "onblur event"

4. hit the enter key

results in a crash on the experimental build.

I tested this on buildID : 2002-03-18-05trunk. 
There was no crash on this build, but when i did steps 1-3, the alert box did 
pop up (alert box should not pop up since the checkbox still has focus ). 
when i hit the enter key, i lose focus from the window.

run the steps described above

Comment 2

[Madhur Bhatia]

another thing i noticed. see the same attached testcase.

1. when i click on the onclick event checkbox --- i see a check mark. when i 
click or hit the enter key on the "ok" button of the alert box --- the checkmark 
disappears.

2. when i click the onblur event checkbox or the onfocus event checkbox --- i do 
not see any checkmark appear, thought the focus remains on the respective 
control.

I get this on a nightly build I just pulled down as well as my branch build.  
Doesn't seem related to the branch changes.  The other comments you mentioned 
about checkmarks are fixed.

Comment 4

[Madhur Bhatia]

verified that the checkmark issue is fixed in the new experimental build.

The crash issue has still to be fixed.

By the definitions on <http://bugzilla.mozilla.org/bug_status.html#severity> and
<http://bugzilla.mozilla.org/enter_bug.cgi?format=guided>, crashing and dataloss
bugs are of critical or possibly higher severity.  Only changing open bugs to
minimize unnecessary spam.  Keywords to trigger this would be crash, topcrash,
topcrash+, zt4newcrash, dataloss.
