RadioChoice and ListView
Hi all,
I'm trying to use a Radio Choice component inside a Listview so that each
list
item has one RadioGroup with three choices. When the form submit button is
pressed,
each selected choice should set a field in the model object of each list
item.
The code below should explain the problem more fully:
/*
The ultimate goal is to set the "status" field in each Participation object
in the participationList of the object below.
*/
public class Experiment {
private String name;
private List<Participation> participationList;
/* Other fields, constructors, getters, setters, etc */
}
public class Participation {
public static final int PARTICIPATED = 1;
public static final int NO_SHOW = -1;
public static final int SHOWED = 0;
private User user;
private int status;
public Participation() {
status = SHOWED; // Default value
}
/* getters, setters, etc */
}
/* This is the web page that is supposed to do the setting*/
public class ParticipationPage extends BasePage {
private static final long serialVersionUID = 1L;
@SpringBean
private ExperimentDAO exDAO;
private DetachableExperimentModel exModel;
public ParticipationPage(Experiment ex) {
exModel = new DetachableExperimentModel(ex, exDAO);
add(new ParticipationForm("form"));
exModel.detach();
}
class ParticipationForm extends Form {
public ParticipationForm(String id) {
super(id);
List<Participation> participationList = exModel.getEx
().getParticipationList();
ListView subjectListView = new ListView("list",
participationList) {
private static final long serialVersionUID = 1L;
/*
I imagine the correct code should be something like
this...?
*/
public void populateItem(final ListItem item) {
Participation participation =
(Participation)item.getModelObject();
item.add(new Label("name", participation.getUser
().getName()));
RadioGroup rg = new RadioGroup("choice");
rg.add(new Radio("participated", new Model(
Participation.PARTICIPATED)));
rg.add(new Radio("no show", new Model(
Participation.NO_SHOW)));
rg.add(new Radio("showed", new Model(
Participation.SHOWED)));
item.add(rg);
}
};
subjectListView.setReuseItems(true);
add(subjectListView);
}
@Override
protected void onSubmit() {
/*
* Somehow I have to set each Participation object in the user's
participationList
* to the choice from corresponding the radio group.
*/
exDAO.persistExperiment(exModel.getEx());
exModel.detach();
}
}
}
Does anyone know how to do this easily? I imagine it's not difficult, I just
can't figure it out
from the examples on the web.
Thanks!

Posted by Carlos Pita <ca...@gmail.com>.
The property model will obtain its target object -the one against which the
property is resolved- from the passed model. So eventually an entity is
loaded from the repository and its associations navigated through property
models. That is to say that property model is not eager but will try to
resolve its property on demand just once per request.

Posted by Alex Pine <al...@gmail.com>.
Thank you Carlos, that fixed the problem! However, I still don't quite
understand why. I guess I don't understand PropertyModel as well as I
thought I did. What does PropertyModel do that allows the ParticipationList
to be referenced across the two requests?
Thanks again!

Re: RadioChoice and ListView
Posted by Carlos Pita <ca...@gmail.com>.
This looks wrong too:
List<Participation> participationList = exModel.getEx
().getParticipationList();
ListView subjectListView = new ListView("list",
participationList) {
if your experiment model is intended to be a detachable one, ie. if you are
loading it from a database or something, then you shouldn't instantiate the
listview with a list but with a model that loads that list (or delegates to
another model that eventually loads the entity to which the collection
belongs...). If you pass the plain collection you are defeating the entire
purpose of having the loadabledetachablemodel in the first place. For
example, use new ListView("list",
new PropertyModel(exModel, "participationList"));

Re: RadioChoice and ListView
Posted by Igor Vaynberg <ig...@gmail.com>.
break in your onsubmit and look at the list that the listview is pointing
to. make sure the data is there, the fact that it isnt being persisted might
be a problem outside of wicket's scope.

Re: RadioChoice and ListView
Posted by Alex Pine <al...@gmail.com>.
I'm sorry to spam the list like this, but I really need help on this. Igor's
solution doesn't seem to change anything. No information is transferred to
the database upon hitting "on submit". If no one knows the solution, does
anyone have any ideas on how I could debug this? Is there some way I can
reference the selections of the radiogroups from the the onSubmit method so
I can see what their values are?
Thanks for any help you can give,
Alex

Thank you for the quick reply, but this fix doesn't seem to work. The
selections are never persisted on form submit. Any ideas?

Re: RadioChoice and ListView
Posted by Igor Vaynberg <ig...@gmail.com>.
problem is here
RadioGroup rg = new RadioGroup("choice");
you are not setting the model for the radiogroup choice so your choices go
no where
RadioGroup rg = new RadioGroup("choice", new PropertyModel(item.getModel(),
"status"));
or leave it as it is and use PropertyListView instead
