Programmatically building EventListener

[Michael Gloegl <mi...@alemo.de>]

Hi all,

I would like to use the (very cool) EventListener AJAX-stuff in Tapestry 
4.1. in our project - however I am facing a little obstacle. Basically, 
the ids of the Elements to listen to are not known when writing the 
Page, due to various complex requirements.

So, simple question: Is it possible to programmatically attach 
EventListeners, for example in renderComponent()? The ids are known on 
component load-time, as they only depend on static component properties 
and the template. (no real application logic required).

Any pointers on where/how something like this could be included?

Thanks in advance,
Michael

Are the ids not known because they are generated ? EventListener
should work with components that are rendered multiple times.. ie:

@EventListener(targets = "myComponent" , events = "onSomething")

works with:

<span jwcid="@For" source="myModel">
    <span jwcid="myComponent" />
</span>
