Re: [jsr-314-open] data payload for ajax calls

The onevent attribute of <f:ajax> can be used to specify a JS

to monitor Ajax calls, which is all well and good. However, the data
payload (I'm not sure why we have to refer to it as a payload), seems
strange because:
1. data.type is always "event". What's the point of that?!?
Sometimes, it's error. See the jsf-demo/ajax-queue demo for an example
that uses this interchangeably.
2. data.name <http://data.name> is really the status of the
Ajax
request. Using "name" for the property seems meaningless. Name of what?
The name of the event. Or, the name of the error. The spec lists them
- there are only a few to choose from. I'm afraid I don't understand
your objection.
3. does it make sense to give the page author acdcess to the actual
XMLHttpRequest object via the data payload? data.xhr, for example?
Is your objection that they could modify the object? Since this is
JavaScript, they can already modify darn near everything anyway. We
could always deliver them a copy of the object, I suppose...
