Ajax chart service
I have a service that generates images for using jfreechart. I want to
convert this service to ajax so that the chart image can load without
reloading the whole page. I have played around with div's and
updateComponent and ResponseBuilder. The ajax response seems to be
generated but the image is never updated. What is the problem? Do I need
to find a way to include Javascript to load the image via scripting? My
ajax works for raw text but not for image services.

I'm using T4? Will this work in tapestry 4.1.3. And if necessary, can you
provide links or sample code on how to handle this in t4? Thanks.

you need not ajax here,
just change src of the image,
first create an action link that can produce an image
then use javascript to switch urls for the image...

IMHO you don't need AJAX for that, becuase AJAX require XML HTTP Request to
client, you don't really need to do that in case you know how your image URL
should looks like. For example if you implementing a zooming functionality
you just need a javascrtip to select an area of the image, then you
calculate (in javascript) coordinate of rendered graph (as subsect of
original image) and just replace the image's URL inside javascript. That's
all, browser will make a request to the server and refreshes the
image.Basically
it's something like
document.getElementById('im').src='img1.jpg'
I'm sure you will find a good replacement in Prototype for "
document.getElement...".
