@EventListener Question

[Janos Mucsi]

Hi
Thanks, Jesse, for your answer.
What if I want to return values from the listener method? Instead of
@EventListener(elements = "myFavoriteDiv", events = "onmouseover")
   public void watchText(BrowserEvent event)
   {
       System.out.println("watch text entered"+event);
   }

I want something like

@EventListener(elements = "myFavoriteDiv", events = "onmouseover")
   public List<State> watchText(BrowserEvent event)
   {
        // get country id from event
        // String countryId = ...;
        List<State> states = someService.getStates(countryId);
        return states;
   }

(Of course, probably it would be a <select> and onChange.) Is there a 
way to do this?

Thanks.
Janos

I'm not sure what you mean, the asynchronous portion should happen
automatically.

It should also behave exactly the same way as your listener method 
would if
it were say a @Submit component listener or @DirectLink listener.  The 
major
difference is that it automatically submits your form if you happen to be
targeting a component that implements IFormComponent. (which most form 
based
Tapestry components do)

Hi

I am new to Tapestry, so excuse my basic question. I am reading
http://tapestry.apache.org/tapestry4.1/tapestry-annotations/index.html

and was wondering how @EventListener implements asynchronous calls. Does
anybody have a sample that behaves like the example:

@EventListener(events = "selectOption", targets = "projectChoose",
submitForm = "taskForm", async=true)
public void projectSelected(IRequestCycle cycle)
{
        
cycle.getResponseBuilder().updateComponent("projectDescription");
        cycle.getResponseBuilder().updateComponent("feedbackBlock");
}


Thanks!
