You should let Wicket set the entered values directly into your Movie
objects:
add(new PropertyListView("movies", moviesModel) {
protected abstract void populateItem(ListItem item) {
item.add(new TextField("name"));
item.add(new DropDownChoice("category", categoriesModel));
...
}
};
In #onSubmit() you'll just have to save the movies in the db.

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:

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.
