Yes it's in the classes directory... I don't understand what could be
wrong... my Home.html is:
<span jwcid="@Wrapper">
<div id="navigation">
<ul>
<span jwcid="@For" source="ognl:visita.menus"
value="ognl:currentMenu" element="li">
<span jwcid="@Insert" value="ognl:currentMenu.name">Menu
name</span>
</span>
</ul>
</div>
</span>

Hmm. Looks ok (but I don't use annotations, either). Are you sure
that the hivemodule.xml file is being copied over to the classes
directory? Check that.
I find it easier (for webapps) to just drop it directly in the WEB-INF
directory. Since you're typically running tomcat with the docBase
pointing back to your project (for development, anyway -- and likely
so if you are using Kent's book) this should work fine.

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
