Hi Henrique,
Answer can be found from javadoc
/**
* Gets whether this component and any children are visible.
* <p>
* *WARNING: this method can be called multiple times during a
request. If you override this*
* method, it is a good idea to keep it cheap in terms of
processing. Alternatively, you can
* call {...@link #setVisible(boolean)}.
* <p>
*
* @return True if component and any children are visible
*/
public boolean isVisible()
{
return getFlag(FLAG_VISIBLE);
}

I am overriding the link's onVisible method to do some conditional
markup. I've realized that this method is actually being call 4 times.
When I add a simple System.out to the following code, I get the
corresponding resut:
MyPAGE.JAVA
public class MyPage extends WebPage {
public MyPage(final PageParameters parameters) {
add(new Link("link") {
public boolean isVisible() {
System.out.println("here i am");
return false;
}
}
}
}
PAGE.HTML
<html><body>
<a href="#" wicket:id="link">The Link</a>
</body></html>
RESULT
here i am
here i am
here i am
here i am
Any ideas why this method is being called 4 times?
Thanks.
