Firefox complains about event.which not being writable (keyboard event handling)

You can reproduce it on firebug with this:

$(document).keypress( function() { alert("broken"); } );

Tested on FF 2.0.0.3 / OSX

I am also getting this error.

here's the error and the error line.

setting a property that has only a getter

[Break on this error] event.which = event.keyCode;

jquery.js (line 2976)

I'm seeing this error while using ExtJS and their custom combo box.

I can confirm this issue. On any key event, jQuery is setting the property "event.which " on this line:

// Add which for keypresses: keyCode

2975 if ( (event.which == null || event.type == "keypress") && event.keyCode != null )

2976 event.which = event.keyCode; <-- here

Which FireFox doesn't seem to like very much.

This is now fixed in Rev [2009]
