Visit obj initialization

Hi,

I have Visit class that is declared in web.xml in <servlet> section
    <init-param>
		<param-name>org.apache.tapestry.visit-class</param-name>
		<param-value>some.path.project.tapestry.Visit</param-value>
	</init-param>
When I try to reach in from some page class (from BasePage), everything is
ok.
	Visit visit = (Visit) getVisit();    

The problem appear when I try to get Visit object in a component. For
example Border.

Here is the listener method from the Border.java (Example from Tapestry in
Action)

public void login(IRequestCycle cycle)
{
           Visit visit = (Visit) cycle.getEngine().getVisit(); <<Always NULL
           if (visit != null && visit.isUserLoggedIn()) 
           return;
.
}
Q. How to initialize Visit to be accessed from not only pages but also
components? 

Thank you much,
Vielen Dank,
:)

Andrey

Actually you can just go:

Visit visit = (Visit) getPage().getVisit();

If Border.java is a component (ie it extends BaseComponent), you can
just use the following:

Visit visit = (Visit) getPage().getEngine().getVisit();
