Hello Rodrigo,
sure i know that the "null" has to be replaced by a model. But my
question was
targeted to the object behind the "dropdown selected option model".
Let me create a more simple example:
<code>
MyComponent.java
----- in constructor -----
IModel<ReplyOptionsCollectingModel> formModel =
Model.<ReplyOptionsCollectingModel> of(new ReplyOptionsCollectingModel())
Form<?> form ...;
form.add(new DropDownChoice("replysForQuestion1", new
PropertyModel<ReplyOption>(formModel, "answerForQuestion1"),
replyOptionsForQuestion1()));
form.add(new DropDownChoice("replysForQuestion2", new
PropertyModel<ReplyOption>(formModel, "answerForQuestion2"),
replyOptionsForQuestion2()));
ReplyOptionsCollectingModel.java
public class ReplyOptionsCollectingModel implements Serializable {
private ReplyOption answerForQuestion1;
private ReplyOption answerForQuestion2;
// ... getter and setter
}
</code>
But because i don't know the count of questions i have to use a
repeating view.
<code>
MyComponent.java
----- in constructor -----
IModel<ReplyOptionsCollectingModel> formModel =
Model.<ReplyOptionsCollectingModel> of(new ReplyOptionsCollectingModel())
Form<?> form ...;
ListView<Question> questions = new ListView(...) {
protected void populateItem(ListItem<Question> item) {
item.add(new DropDownChoice("replysForQuestion", new
PropertyModel<ReplyOption>(formModel, I_dont_know_what_to_add_here),
replyOptionsFor(item.getModelObject())));
}
}
form.add(answers);
ReplyOptionsCollectingModel.java
public class ReplyOptionsCollectingModel implements Serializable {
private Map<Question, ReplyOption> answerForQuestions;
}
</code>
Or do you mean that CompoundPropertyModel has more "features"
handling the indexed-property stuff?
Thanks for your support

Have you tried using CompoundPropertyModels? In that way you could bind a
property to the dropdown, instead of using "null"
