Cannot inject visit object

[Henrik Schlanbusch <he...@enovate.no>]

Hi

I have a problem with injecting a "good old" visit object.

I do the following:

<contribution configuration-id="tapestry.state.ApplicationObjects">
        <state-object name="visit" scope="session">
            <create-instance class="no.imb.bite.framework.BiteVisit"/>
        </state-object>
    </contribution>

and in my BasePage i do the following:

@InjectState("visit")
public abstract BiteVisit getVisit();

As far as I can see, that should be all that 
is to it, but when I try to 
access the get visit method, the following exception occurs:

 Error at
jar:file:.../WEB-INF/lib/tapestry-framework-4.1.3.jar!/META-INF/
tapestry.state.xml,
