Here's a little more code. You can see that I add the PropertyListView
to moviesForm...My listView (movieList) is a LoadableDetachableModel,
so it doesn't have the getModelObject() method. I'm still not quite
sure how to get access to the form details in onSubmit().
Form moviesForm = new Form<ValueMap>("moviesForm") {
/**
* Show the resulting valid new movie
*/
@Override
public final void onSubmit() {
Session session =
HibernateUtil.getSessionFactory().getCurrentSession();
session.beginTransaction();
for (Movie movie : movieList.getModelObject()) {
session.save(movie);
}
session.getTransaction().commit();
}
};
// Add movieListView of existing movies
moviesForm.add(new PropertyListView<Movie>("movies", movieList) {
@Override
public void populateItem(final ListItem<Movie> movieItem) {
final RatingModel rating = new
RatingModel(movieItem.getModelObject().getRating());
movieItem.add(new
TextField<String>("name").setType(String.class));
movieItem.add(new DropDownChoice<Category>("category",
Arrays.asList(Category.values()), new
EnumChoiceRenderer<Category>(this)));
movieItem.add(new RatingPanel ("rating", new
PropertyModel<Integer>(rating, "rating"), 5, new
PropertyModel<Integer>(rating, "numberOfVotes"), false) {
@Override
public boolean onIsStarActive(int star) {
return rating.isActive(star);
}
@Override
public void onRated(int newRating,
AjaxRequestTarget target) {
movieItem.getModelObject().setRating(newRating);
rating.updateRating(newRating);
Session session =
HibernateUtil.getSessionFactory().getCurrentSession();
session.beginTransaction();
session.update(movieItem.getModelObject());
session.getTransaction().commit();
movieList.detach();
}
});
movieItem.add(new Link("removeLink") {
@Override
public void onClick() {
Session session =
HibernateUtil.getSessionFactory().getCurrentSession();
session.beginTransaction();
session.delete(movieItem.getModelObject());
session.getTransaction().commit();
movieList.detach();
}
});
}
}).setVersioned(false);
add(moviesForm);
