hmm...This is an event handler for ajax action. I access it via ajax('/somepage:event') at client side. I don't see any problem for Tapestry to handle the json return value. And it works if I skip the getMarkup for the block. The client receives the json string without problem.

Tapestry does NOT accept JSONObject as a return value from a component event.
If you want to make a JSONObject available in your javascript, you should
use AjaxResponseRenderer.
