T4.1.2 How to generate URL to the listener method

Hi, All.

How can I generate URL for the listener method in my component? I need that
for my javascript function that must send async request to that URL. I can't
use DirectLink component because the element that will send request is
generated dynamically in another javascript function on the client side.

Thanks.

You have to use the corresponding IEngineService service for the type of url
you are generating.. That is how everything in the system (including form
urls) are generated.  Each service has different requirements on the object
type passed in but it's all more or less like:

@InjectObject("service:tapestry.services.DirectService")
public abstract IEngineService getDirectService();

public String getUrl()
{
    String url = getDirectService().getLink(false, new
DirectServiceParameter(/* params */)).getUrl();

    return url;
}

Services can be found in hivedoc linked to off of:
