Status: UNCONFIRMED

(Core :: XUL, defect)

Description

[alexander :surkov (:asurkov)]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.0; ru-RU; rv:1.7.5) Gecko/20041108 Firefox/1.0 (ax)

I fire event from dialog to parent window. I guess when parent window handles
event then handled event object differs from sended event object.

I create event (dialog window):

var event=document.createEvent("Events");
event.initEvents("someevent", true, false);
event.someprop="hello";
parentwnd.dispatchEvent(event);

I handle event (parent window):
event.someprop is undefined

Reproducible: Always

The native event object is probably rewrapped when it gets into script in the
other window...

Is it right when it rewrapped?

Comment 6

[Boris Zbarsky [:bzbarsky]]

Yes.  I believe we rewrap events for security reasons.

Comment 7

[alexander :surkov (:asurkov)]

Is there workaround when I want to pass some information with event?
