Hello users and developers!

I have template:

<t:zone t:id="output"> ${value} </t:zone>
<t:actionlink t:id="update" zone="output">UPDATE</t:actionlink>

And page class:

@Persist
private int value;
        
@InjectComponent("output")
private Zone output;

@Inject
private Request request;
        
public Object onActionFromUpdate() {
        value++;
        if (request.isXHR()) {
                return output.getBody();
        } else {
                return null;
        }
}

This code almost from tapestry example.

When I click on link, browser send two request: first using AJAX (POST) and
secondary ordinary link behavior (GET).

Just like there are no "return false" on link event handler in javascript.

How I can avoid this behavior? I need only one AJAX request.
