No DOM MutationEvents for changes of text data

           Summary: No DOM MutationEvents for changes of text data
           Product: Xerces-J
           Version: 1.4.4
          Platform: PC

Hi again.

I'm still on DOM event usage, with Xerces 1.4.4.
After turning on DOM MutationEvents, the event handler attached to the
document node receives quite many events, but I do not get any ones
reflecting changes within text nodes.

Debugging the methods involved, I see that at DocumentImpl line 1048 that the
MutationEvent created has a null value as target, whereas the DOM level 2
Events specification v1.0 says in section 1.6.4: "The target of this event
is the CharacterData node". Well, maybe that value is set afterwards. I did
not understand all functionality in the code called afterwards.

Finally I tried to register a non-capturing event-listener as well by adding
this line to my code:
((org.w3c.dom.events.EventTarget)n).addEventListener(org.apache.xerces.dom.e
vents.MutationEventImpl.DOM_CHARACTER_DATA_MODIFIED, this, false);
.....and got the event!
But again the target of the event is the DeferredDocumentImpl (where I
attached my event listener) and not the text node that was changed.

- Why is the target wrong?
- Why do I have to use a non-capturing event listener to get this event,
while I am able to receive all others with capturing ones?
