The above is what I usually do, but lately I switched to use #script:
and a #replaceWith:. Because that way I can handle also callbacks, and
other other things in a single HTTP roundtrip instead of performing a
#callback:/#onSuccess:, also the code is easier to implement. It's
heretic, but I found it to be better.


So, let's say:
html anchor
  onClick: ((html jQuery ajax
		callback: [self doSomething])
			onSuccess: ((html jQuery id: #id)
				load html: [:r | self renderOn: r ]))).

Is converted to this:

html anchor
  onClick: (html jQuery ajax script: [:s |
		self doSomething.
		s << ((html jQuery id: #id) replaceWith: [:r |
			self renderOn: r ])
		]).


Maybe the replaceWith: doesn't trigger the "onLoad" event?


I should write a vanilla example to test the different cases. I'll try
to do it tomorrow.

Regards!
