Re: [Wicket-user] setResponsePage question

it's just a sketchy databinder related project i was still implementing.

Okay I have this code in the HomePage,

add(postNew = new Link("postNew"){
            public void onClick(){
                setResponsePage(new RecordInputPage());


            }
        });
        add(viewList = new Link("viewList"){
            public void onClick(){
                setResponsePage(new RecordListPage());

            }
        });

RecordInputPage contains an InnerClass Form and then RecordListPage needs to refer back to RecordInputPage so as to edit a Record. Both Classes extends the HomePage. I need to reference the Inner Class Form in RecordInputPage from RecordListPage and yet be in sync with the Hibernate Session that was automatically created by DataForm in RecordInputPage. What do i do?

Snippet from RecordInputPage

public class DevForm extends DataForm {

        private RequiredTextField nick;
        public DevForm(String id){
            super(id, Developer.class);

            add(nick = new RequiredTextField("nickname"));
            add(new RequiredTextField("name"));
            add(new TextField("mobile"));
            add(new TextArea("skillSummary"));

            FeedbackPanel f = new FeedbackPanel("feedback");

            add(f);
        }

    }

Snippet from RecordListPage

       IModel devList = new HibernateListModel(getString("query"));
        cp.add(new PropertyListView("devView", devList) {
            protected void populateItem(final ListItem item) {
                Developer dev = (Developer) item.getModelObject();
                item.add(new Link("editLink"){
                    public void onClick(){
                     ///WHAT DO I DO HERE TO RETURN TO THE RecordInputPage Class so as to edit this item

                    }
                });
                item.add(new Label("nickname1",dev.getNickname()));
                item.add(new Label("name1", dev.getName()));
                item.add(new Label("mobile1",dev.getMobile()));
                item.add(new Label("skillSummary1",dev.getSkillSummary()));

}
});

I have a One-Class-Inner-Classes implementation that works fine but it gets clumsy as the fields to populate grows which is why i am trying to seperate everything to classes. I have messed around with these and Wicket keeps injecting these errors to my face:).

Caused by: org.hibernate.TransientObjectException: The instance was not associated with this session
    at org.hibernate.impl.SessionImpl.getIdentifier(SessionImpl.java:1358)
    at net.databinder.models.HibernateObjectModel.setPersistentObject (HibernateObjectModel.java:72)
    at net.databinder.models.HibernateObjectModel.<init>(HibernateObjectModel.java:64)

    at wicket.markup.html.link.Link.onLinkClicked(Link.java:183)
    ... 29 more

Please how do i go about these. or maybe i should ignore the Databinder framework and try to implement it directly with Hibernate.

Thank You
