problems portlet eventRequest.setAttribute

[jishin]

Hi,

I am facing a problem with event handling method in Spring portlet mvc 3.

Inside the event method (public final void receiveMessage) i added an attribute into the model

model.addAttribute("receivedMessage", msg);

but the attribute is not available in the render method executed after the event request (ofcourse, ${receivedMessage} in JSPs is also empty).

i also tried request.setAttribute("receivedMessage", msg) But no result.


The complete code,

@Controller
@RequestMapping("VIEW")
public class ReceiveMessageController {
    
    /** Log. */
    private Log log = LogFactory.getLog(ReceiveMessageController.class);

    @RequestMapping
    public final String viewMessage(final RenderRequest request, 
            final RenderResponse response, final Model model) {
        log.debug("inside ReceiveMessageController.viewMessage");
        
        if (!model.containsAttribute("receivedMessage")) {
            log.debug("receivedMessage is empty");
            model.addAttribute("receivedMessage", "no message");
        }
        return "message";
    }

    @EventMapping(value = "{http://jishin.org/events}onMessage")
    public final void receiveMessage(final EventRequest request, 
            final EventResponse response, final Model model) {
        log.debug("inside ReceiveMessageController.receiveMessage");
        Event event = request.getEvent();
        String msg = (String) event.getValue();
        log.debug("ReceiveMessageController received message = " + msg);
        
        model.addAttribute("receivedMessage", msg);
    }
}

The liferay portal log,

INFO: DEBUG - inside ReceiveMessageController.receiveMessage

INFO: DEBUG - ReceiveMessageController received message = Hello World

INFO: DEBUG - inside ReceiveMessageController.viewMessage

INFO: DEBUG - receivedMessage is empty

Am i doing something wrong, or Is it a bug in Spring Portlet MVC 3 ?

Thanks in Advance,
Jishin
