304786 - dynamically inserting/adding xul:script via DOM doesn't work

Status: NEW

User-Agent:       Mozilla/5.0 (X11; U; Linux ppc; en-US; rv:1.7.10) Gecko/20050730 Firefox/1.0.6 (Debian package 1.0.6-2)

When adding a <script> node to a document dynamically (from within JavaScript),
the behaviour between HTML and XUL differs. In HTML, the contained JavaScript
code is executed. In XUL, it is not.
In order to write dynamic XUL applications, it would be helpful to have the
added JavaScript nodes executed as well.
The two testcase files demonstrate the behaviour: With HTML, a message box pops
up, while with XUL, the node gets added (as can be confirmed with DOM
Inspector), but no message box appears.

Reproducible: Always

confirm with a 2005-08-15 deerpark build on winxp, over to dom

The basic problem is that xul:script is not implemented in the content node (because nothing in XUL is!) but in the XUL parser...

[Jonas Sicking (:sicking) No longer reading bugmail consistently]

A workaround until this is fixed:

change 

document.createElement('script')

to

document.createElementNS('http://www.w3.org/1999/xhtml', 'script')

This should work fine even in XUL documents.
