Fix for TAP5-624, Support for javascript callbacks on zone update

["Blower, Andy" <An...@proquest.co.uk>]

Having just updated our app to use T5.1.0.4, I checked out the changes made for TAP5-624 to support javascript callbacks on a zone update. I'm a bit surprised at the solution for this which is to fire a client side event. I thought that it would have used the JSON object returned for partial page renders which already has a script: element, allowing addScript() or something similar to be used.

Is there a reason that this isn't possible or isn't a good idea? It seemed an obvious thing to me since the facility is already there but just needs exposing to users.

Anyone have an opinion on this? (just wondering if it got lost among the Tapestry is beautiful discussion... ;-)

I agree. The most common use case where i've missed this feature is
for handling different results that can come from some server side
execution.
With the current fix i would have to parse the returned JSON on the
client side and code all logic there.

If addScript() support was added to XHR requests i could implement
this logic on the page class where it makes sense.
