You're instantiating an ArrayList, not a Person object.

Oki - so this is what I have
classes/META-INF/hivemodule.xml
//With some help from Tongs book...
<?xml version="1.0"?>
<module id="org.project.web.tapestry4.pages" version="1.0.0">
<contribution configuration-id="tapestry.state.ApplicationObjects">
<state-object name="person" scope="session">
<create-instance class="java.util.ArrayList"/>
</state-object>
</contribution>
</module>
//Home.java
@InjectState("person")
public abstract Person getPerson();
public abstract void setPerson(Person person);
...
person = getPersonManager().getPersonByUsername(yahooUsername);
setPerson(person);
cycle.activate(main);
//Main.java
public abstract Person getPerson();
public abstract void setPerson(Person person);
//Main.html
<span jwcid="@Insert" value="ognl:person.username"/>
Still no output though, person.username = null... I know that the
property is there because I can set it manually if I do
nextpage.setPerson(person);
Anything I've missed maybe??? Thanks!
