The error you get is probably due to the fact that it is not an ajax request. you can only return blocks from event methods when making ajax requests.
you have to make the request with Ajax.request(...) or by using tapestry default ajax mechanism. (<t:form t:zone="....">...) hope it helps! 2008/3/19, Martin Kersten <[EMAIL PROTECTED]>: > I see.
