Re: json + prototype + ajax?

I am curious as to the pattern used to make the async calls, what method
of return is used here?

I see two possible patterns which would be useful:

1) JSON compressed objects. This will require more processing on the
front end to pull the data and format the HTML. I like leaving this in
the front end code personally. This is currently implemented using the
JSONServiceEventHandler request handler.

2) Screen Widget based HTML return. The Ajax request makes a simple call
which returns a HTML fragment (developed using screen widgets). The
return is then just plugged in by updating the element content (innerHTML).

Either of these patterns is fine by me, and I believe that for most
applications a combination of the two would be necessary.

I am sure there are many other ways to accomplish the same thing, but
since there is so much effort about to begin around 'Ajaxing' OFBiz
making sure things are consistent is #1 priority.

I'm curious as to what other 'patterns' people have come up with (if any).
