You'll probably want to contribute it to AjaxComponentEventResultProcessor though.

Hi You will have to create your own ComponentEventResultProcessor and contribute it in your AppModule class : public void contributeComponentEventResultProcessor( MappedConfiguration<Class, ComponentEventResultProcessor> configuration) { configuration.addInstance(net.sf.json.JSONObject.class, YouProcessor.class); } 2010/7/8 Borut Bolčina<borut.bolc...@gmail.com>Hello, Is it possible to configure return types? In one of my event methods I was trying to return net.sf.json.JSONObject instead of org.apache.tapestry5.json.JSONObject and got this error message: [ERROR] TapestryModule.RequestExceptionHandler Processing of request failed with uncaught exception: A component event handler method returned the value {"birthDay":"","birthMonth":"","birthYear":"","gender":"male","postOfficeNumberAndName":"1236 Trzin"}. Return type net.sf.json.JSONObject can not be handled. Configured return types are java.lang.Class, java.lang.String, org.apache.tapestry5.Link, org.apache.tapestry5.StreamResponse, org.apache.tapestry5.ajax.MultiZoneUpdate, org.apache.tapestry5.json.JSONArray, org.apache.tapestry5.json.JSONObject, org.apache.tapestry5.runtime.Component, org.apache.tapestry5.runtime.RenderCommand. org.apache.tapestry5.runtime.ComponentEventException: A component event handler method returned the value {"birthDay":"","birthMonth":"","birthYear":"","gender":"male","postOfficeNumberAndName":"1236 Trzin"}.

[at context:Index.tml, line 20] My event method: @OnEvent(component = "email", value = "blur") public JSONObject checkIfUserWithThisEmailExists(String value) { UserData userData = new UserData(); if(value.equals("b...@example.com")) { userData.setPostOfficeNumberAndName("1236 Trzin"); userData.setGender("male"); } else { logger.info("Bob does not exist."); } JSONObject jsonObject = (JSONObject) JSONSerializer.toJSON(userData); return jsonObject; } The reason I used net.sf.json.JSONObject is because it offers great conversion and construction capabilities to/from JavaBeans/XML/JSON. Have a look at http://json-lib.sourceforge.net/snippets.html. Is it possible or do I have to construct the org.apache.tapestry5.json.JSON object by hand? Thanks, Borut
