Thanks for answer.

The joke is, its not my component. Its component in Tapestry-jquery module. So if i understood correctly... ....it is a bug and i should report it, isn't it?

BR,

Hi guys,

Hi!

Caused by: org.apache.tapestry5.ioc.util.UnknownValueException: A component event handler method returned the value {}. Return type org.apache.tapestry5.json.JSONObject can not be handled.

These "Return type XXX can not be handled" messages usually mean that you tried to return an AJAX value in a non-AJAX request or vice-versa. In your AJAX event handler methods, always have a "if (request.isXHR()) { return null; }" (where request is @Inject private Request request) check or something like the @Ajax annotation written by Taha in his blog.
