Status: REOPENED

(Toolkit :: Autocomplete, defect, P3)

Description

[ivodsh]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1) Gecko/20061010 Firefox/2.0
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1) Gecko/20061010 Firefox/2.0

The url I specified is a login screen. the onkeydown event is handled by javascript in order to post back. 
When typing in User Name an auto complete popup may appear if you select an item from this popup and press ENTER then the form is submitted surprisingly. and the User name field is not prefilled.
The IE behavior is not to fire onkeydown event when enter is pressed, because the enter action semantically is not intended for the underlying page but for the browser.


Reproducible: Always

Steps to Reproduce:
1.Go to the url http://www.dotnetnuke.com/Home/tabid/510/ctl/Login/Default.aspx
2.Type for example "user1" in user name field
3.press login - unsuccessfull login appears
4.then go again in user name field an type "u" only - the auto complete appears
5.select scroll the the user1 item using the up down arroys
6.now pres ENTER
7. the form submits and the user name field has only "u"

Actual Results:  
onkeydown event is fired with keycode=13
the form submits and the user name field has only "u"

Expected Results:  
No onkeydown should fire

If I'm reading it right, bug 286933 eats the keypress event, but apparently not the keydown.
