Having trouble with creating an ASO

[Dan Adams]

I'm trying the following in my hivemind.xml:
<contribution configuration-id="tapestry.state.ApplicationObjects">
          <state-object name="user-data" scope="session">
                <invoke-factory
object="instance:org.apache.tapestry.engine.state.NamedClassStateObjectFactory,className=com.ifactory.cms.UserData"
 />
          </state-object>
</contribution>

and I'm getting a NPE in NamedClassStateObjectFactory:

    public Object createStateObject()
    {
        try
        {
            Class c = _classResolver.findClass(_className); !!!! NPE IS
HERE

            return c.newInstance();
        }
        catch (Exception ex)
        {
            throw new
ApplicationRuntimeException(StateMessages.unableToInstantiateObject(
                    _className,
                    ex), getLocation(), ex);
        }
    }

But before I was doing it this way with no problem:

        <contribution configuration-id="tapestry.state.ApplicationObjects">
          <state-object name="user-data" scope="session">
                <invoke-factory object="service:UserDataFactory" />
          </state-object>  
        </contribution>

  <service-point id="UserDataFactory"
interface="org.apache.tapestry.engine.state.StateObjectFactory">
        <invoke-factory service-id="hivemind.BuilderFactory">
                <construct class="UserDataFactory" />
    </invoke-factory>
  </service-point>

Where UserDataFactory just extended NamedClassStateObjectFactory and set
className. Any suggestions?
