149620 - DOMSubtreeModified does not bubble up to xbl handler

Status: NEW

(Core :: DOM: Events, defect, P5)

Description

[Justin Kirby]

Inserting a node into the xbl element DOMSubtreeModified event does not trigger
the event in the xbl's handler.

<handler event="DOMSubtreeModified" action="alert('inserted');"/>

The action alert will never be called.

Changing the event to DOMNodeInserted, however, does trigger the action.

testcase, as simple as I could make it

[Justin Kirby]

The test case is rather simple.

Just extract the tarball and enter file:///path/to/bug149620.xul in the url bar.

Click the Add button and it calls the Add() method in the xbl element, which in
turn modifies the xml dom tree by inserting another label into the anonymous
content.

There are two handlers in the binding. The DOMNodeInserted event is commented
out. If you comment out the DOMSubtreeModified handler and uncomment
DOMNodeInserted handler, then the alert will popup.

However, no alert will popup on the DOMSubtreeModified handler. I can only
assume this is because the event is either never dispatched or does not
correctly travel up the dom tree.

Oh man, sorry, I forgot, that event is not implemented yet...

According to this testcase, XUL doesn't support the DOMSubtreeModified event
listener properly.

Incidentally, I see some funky breakage of replaceChild() in DOM Inspector.
