Greetings, the short answer to your question is that we are in the process
of completely rewriting the Processing Model section of the XForms spec,
once this is complete the answer to your question should become clear.

The new processing model will only be available in the next version of the
spec. I suspect that next question might be when will this be available.
I'm afraid that I'm not able to say when but I will point out that we are
supposed to relese updated Working Drafts at approximately 3 month
intervals, the last draft was dated: 28 August 2001

Regards, Roland

Subject: event target

I have recently joined this list, so please forgive me if these are
'old' questions...

Further to the thread below, would it be correct to infer from the
spec. (in particular 11.4.6) that the 'xforms-instance-changed' event
is targetted at the form control node and NOT the instance data node?

If so, that would mean that an event listener that registered with a
form control node would handle an xforms-value-changing event followed
by an xforms-instance-changed event for each 'change' to the
control...correct? And if multiple form controls ref the same instance
data, each one of them would fire an xforms-instance-changed event
when that data changed?

How might one attach a listener to the form that is called once (and
only once) when instance data changes, irrespective of the number of
form controls with binding to that data?

Many thanks,
