Hi -- Here's what we did...
1 - get the data you want in a python object
2 - Use simplejson
http://simplejson.googlecode.com/ to
serialze that to javascript and write it to an http response w/ the
right "Content-type" header.
3 - Call the json from javascript (e.g. using jQuery's $.getJSON)
4 - call setValue a bunch -- viola
Hope that helps,
Kyle
