596224 - Firefox 4 createDocument - overlay document creation is failing in XUL namespace inside XPCOM component

Status: RESOLVED WONTFIX

(Core :: XUL, defect, P1)

Description

[Sri]

User-Agent:       Mozilla/5.0 (Macintosh; Intel Mac OS X 10.5; rv:2.0b5) Gecko/20100101 Firefox/4.0b5
Build Identifier: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.5; rv:2.0b5) Gecko/20100101 Firefox/4.0b5

Inside my JS XPCOM component, i'm trying to create an overlay document
as follows.

var domDocument = Components.Classes["@mozilla.org/xul/xul-document;
1"].createInstance(CI.nsIDOMDocument);
var _mDocument = domDocument.implementation.createDocument("http://
www.mozilla.org/keymaster/gatekeeper/there.is.only.xul", "overlay",
null);

The above code is failing with this error.

Component returned failure code: 0x80040111 (NS_ERROR_NOT_AVAILABLE)
[nsIDOMDOMImplementation.createDocument]

The code is working fine in FF 3. It's failing in Firefox 4.

Is this a side effect of dropping remote XUL? (bug 546857)

Reproducible: Always

Creating documents using contract ids is a bad idea, so not blocking on this. Can you work around this?

Hi Jonas,

Do we have any updates on this issue?

Thanks, Paul.

If this is still a problem, we're unlikely to spend enough resources to fix it. We're investing in other solutions for both XUL and for addons these days. I recommend looking at WebExtensions instead.
