Basically, you are using Ajax to trigger an action. AjaxFormLoop expects certain things (context) to be in the Tapestry environment (see @Environmental) and it isn't. This is why you get the exception.
I haven't used AjaxFormLoop myself, and don't know how to help you further, but perhaps somebody can help here. Now your question is worded so someone can answer it I think...
