Use a LoadableDetachableModel to load a fresh list of movies on each
request.

I'm creating a small app based on the guestbook:
http://www.wicket-library.com/wicket-examples/guestbook/?1
In the guestbook app, the page view is updated every time a new
comment is added. The variable commentList is initialized at the top
like this
private static final List<Comment> commentList = new ArrayList<Comment>();
// Add commentListView of existing comments
add(new PropertyListView<Comment>("comments", commentList)
{
@Override
public void populateItem(final ListItem<Comment> listItem)
{
listItem.add(new Label("date"));
listItem.add(new MultiLineLabel("text"));
}
}).setVersioned(false);
I wanted to use a database instead, so I made the following changes
private List<Movie> movieList = new ArrayList<Movie>();
Session session =
HibernateUtil.getSessionFactory().getCurrentSession();
session.beginTransaction();
movieList = session.createQuery("from Movie").list();
session.getTransaction().commit();
// Add commentListView of existing comments
add(new PropertyListView<Movie>("movies", movieList) {
@Override
public void populateItem(final ListItem<Movie> listItem) {
listItem.add(new
TextField<String>("name").setType(String.class));
listItem.add(new DropDownChoice<Category>("category",
Arrays.asList(Category.values()), new
EnumChoiceRenderer<Category>(this)));
listItem.add(new Label("rating"));
}
}).setVersioned(false);
With this change, all the items in the database come up when the page
first loads, but not after each new item is added to the database. I
have to clear out the URL and load the page fresh to see what has been
added since the last fresh load.
I did try resetting movieList in the onSubmit function to load the
current database items into the variable movieList, but that still
doesn't update the list.
Any idea how to update movieList after each new item is submitted.
