form processing for multiple objects

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.

Re: form processing for multiple objects

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?

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.

So you're already using PropertyListView, fine.

What's your problem once again?

Re: form processing for multiple objects

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

ValueMap values = getModelObject();

values is null...

Re: form processing for multiple objects

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

Re: form processing for multiple objects

In reply to this post by Daniel Watrous-2

Note that I can access the objects that I populate using a
PropertyListView individually just fine.

What I am trying to do now is access them as part of a larger form so
that I can update multiple items at once. I was hoping to be able to
iterate through the items that the PropertyListView had rendered so
that I can update them one by one. That's where I'm failing. That Form
and onSubmit are defined outside of the PropertyListView.

I'm sorry if I'm not explaining this very well.

Re: form processing for multiple objects

In reply to this post by Sven Meier

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();

Re: form processing for multiple objects

I ended up with something similar (see also this post:
http://apache-wicket.1842946.n4.nabble.com/Add-new-items-to-a-list-within-a-form-by-ajaxlink-td2017446.html)

http://paste.pocoo.org/show/539351/

I created a class level variable that would hold my PropertyListView
which made it available to the my onSubmit() method in the form.

Thank you so much for your help.

Daniel
