Do you have the ValueMap usage from a Wicket example (e.g. Guestbook)?
You don't seem to have any code that wires a ValueMap into your form.
The following should be enough:
@Override
public final void onSubmit() {
Session session =
HibernateUtil.getSessionFactory().getCurrentSession();
session.beginTransaction();
for (Movie movie : listView.getModelObject()) {
session.save(movie);
}
session.getTransaction().commit();
}
Hope this helps

The problem is that I can't seem to access the form submitted values
in onSubmit().
ValueMap values = getModelObject();
values is null...

So you're already using PropertyListView, fine.
What's your problem once again?

Let me give a little more detail. The way that markup is managed is
through this:
// 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() {
System.out.print(movieItem.getModelObject().getId());
Session session =
HibernateUtil.getSessionFactory().getCurrentSession();
session.beginTransaction();
session.delete(movieItem.getModelObject());
session.getTransaction().commit();
movieList.detach();
}
});
}
}).setVersioned(false);
I suppose that means that I'm not actually adding new items to the
list as a form. Maybe what I need is to treat the entire component as
a form from the beginning. I'm just not sure exactly how to do that.
Any ideas?

I have populated a form with values representing several different
objects. This is what my markup looks like:
<form wicket:id = "moviesForm" id = "moviesForm">
<span wicket:id = "movies" id = "movies">
<a wicket:id = "removeLink">(remove)</a>
<input type="text" wicket:id="name" class="nospam"/>
<select wicket:id="category"/>
<span wicket:id="rating">rating</span>
<br />
</span>
<input type = "submit" value = "Update Movies"
id="formsubmit"/>
</form>
The span is reproduced for each object that I pull from a database.
There is a different identifier for each span, as you can see here:
http://screencast.com/t/l8pLGZnJVn8
I want to be able to access these objects when I click submit the
form, but I'm not sure how to get access to them. This is what I have
tried so far:
Form moviesForm = new Form<ValueMap>("moviesForm") {
/**
* Show the resulting valid new movie
*/
@Override
public final void onSubmit() {
ValueMap values = getModelObject();
// perform validation and security here
if (StringUtils.isBlank((String) values.get("name"))) {
error("Received bad input!!!");
return;
}
Session session =
HibernateUtil.getSessionFactory().getCurrentSession();
session.beginTransaction();
Movie movie = new Movie();
movie.setName((String) values.get("name"));
movie.setCategory((Category) values.get("category"));
session.save(movie);
session.getTransaction().commit();
}
};
The ValueMap values comes back null from getModelObject(). Any
pointers for me to get these objects back in a way that I can easily
update them?
Thanks.
