Application State Objects and Hivemind...

[GbT]

Hi to all,
I am in trouble getting application state objects to work... I want to
use a class named Visita in my package com.mypackage... and write this
hivemind.xml file in src/META-INF as explained in Kent Tong book:

<?xml version="1.0"?>
<module id="com.mypackage" version="1.0.0" package="com.mypackage">
        <contribution configuration-id="tapestry.state.ApplicationObjects">
                <state-object name="visita" scope="session">
                        <create-instance class="com.mypackage.Visita"/>
                </state-object>
        </contribution>
</module>

I'm using cayenne for the persistence... Visita.java is simple:

package com.mypackage;
import java.io.Serializable;
import java.util.List;
import org.apache.tapestry.IRequestCycle;
import org.objectstyle.cayenne.access.*;
import org.objectstyle.cayenne.query.*;
import com.mypackage.logic.*;

public class Visita implements Serializable {
    protected DataContext dataContext;
    protected Menu currentMenu;
    public Visita() {
        super();
        this.dataContext = DataContext.createDataContext();
    }
    public DataContext getDataContext() {
        return dataContext;
    }
        public void setCurrentMenu(Menu menu) {
                currentMenu = menu;
        }
        public List getMenus() {
        if (currentMenu!=null) {
                return currentMenu.getSons();
        }
        SelectQuery query = new SelectQuery(Menu.class);
                return getDataContext().performQuery(query);
    }
}

I inject visita in Home.java with:
@InjectState("visita")
public abstract Visita getVisita();

But everytime I try to access Home to display visita.menus... i get this error:

Unable to read OGNL expression '<parsed OGNL expression>' of
[EMAIL PROTECTED]: visita

... 'visita' is not a declared application state object.

What's wrong???

And what's the best way to store the currentMenu a user is displaying?
I choose to use the Visita.currentMenu object (in the session).

Thanks
