[jQuery] jquery.js in XUL dialog

[jQuery] jquery.js in XUL dialog


Hi all,
I develop Firefox extention and like to use jQuery. It works when I
use it from overlay, but doesn't when insertede in dialog:
<overlay xmlns="http://www.mozilla.org/keymaster/gatekeeper/
there.is.only.xul" orient="vertical">
    <script src="jquery.js"/>
    <script src="myscript.js"/>
In this case I can use jQuery from myscript.js
But in this case
<dialog id="mydialog" buttons="accept,cancel" buttonpack="center"
xmlns="http://www.mozilla.org/keymaster/gatekeeper/
there.is.only.xul"
title="My Dialog
ondialogaccept="onAccept();">
<script src="jquery.js"/>
all XUL controls inside dialog are not shown (except standard
buttons).
When I remove
<script src="jquery.js"/>
the dialog works just fine
When I change dialog to window the controls are shown also (without
standard buttons, of course).
Firefox 3.0.7, jQuery 1.3.2, Windows XP SP3
Is it jQuery bug?
