Let me use the real situation:
Client 1--* Account 1--* Context 1--* Schedule
Here is the code simplified as much I can. If you think I have to add
something else just tell me:
public class AssignationPanel extends Panel {
@SpringBean
private WSServicesIF services;
private IModel<List<String>> assignationRolsModel = new
AssignationRolsModel();
public AssignationPanel(String id, IModel<AssignationBean> model) {
super(id, model);
final Form<Void> form = new Form<Void>("form");
final PropertyModel<Client> selectedClient = new
PropertyModel<Client>(model, "client");
final PropertyModel<Account> selectedAccount = new
PropertyModel<Account>(model, "account");
final PropertyModel<ContentType> selectedContext = new
PropertyModel<ContentType>(model, "context");
final Component clientSelector = new DropDownChoice<Client>("clients",
selectedClient, new ClientsModel(services), new
ClientRenderer()).setNullValid(false);
final Component accountSelector = new DropDownChoice<Account>("accounts",
selectedAccount, new AccountsOfClientModel(selectedClient, services), new
AccountRenderer()).setNullValid(false).setOutputMarkupId(true);
final Component contextSelector = new
DropDownChoice<ContentType>("contexts", selectedContext, new
ContextsOfAccountModel(selectedAccount, services), new
ContextRenderer()).setNullValid(false).setOutputMarkupId(true);
final Component scheduleSelector = new
DropDownChoice<Schedule>("schedule", new PropertyModel<Schedule>(model,
"schedule"), new SchedulesOfContextModel(selectedContext, services), new
ScheduleRenderer()).setNullValid(false).setOutputMarkupId(true);
clientSelector.add(new AjaxFormComponentUpdatingBehavior("onChange") {
@Override
protected void onUpdate(AjaxRequestTarget target) {
target.addComponent(accountSelector);
target.addComponent(contextSelector);
target.addComponent(scheduleSelector);
}
});
accountSelector.add(new AjaxFormComponentUpdatingBehavior("onChange") {
@Override
protected void onUpdate(AjaxRequestTarget target) {
target.addComponent(contextSelector);
target.addComponent(scheduleSelector);
}
});
contextSelector.add(new AjaxFormComponentUpdatingBehavior("onChange") {
@Override
protected void onUpdate(AjaxRequestTarget target) {
target.addComponent(scheduleSelector);
}
});
form.add(clientSelector);
form.add(accountSelector);
form.add(contextSelector);
form.add(scheduleSelector, new
SimpleMessageComponentFeedbackPanel("scheduleError", scheduleSelector));
add(form);
}
}
public class ClientsModel extends LoadableDetachableModel<List<Client>> {
private WSServicesIF services;
public ClientsModel(WSServicesIF services) {
this.services = services;
}
@Override
protected List<Client> load() {
return new ArrayList<Client>(services.getClients());
}
}
public class AccountsOfClientModel extends
LoadableDetachableModel<List<Account>> {
private WSServicesIF services;
private IModel<Client> client;
public AccountsOfClientModel(IModel<Client> client, WSServicesIF services)
{
this.services = services;
this.client = client;
}
@Override
protected List<Account> load() {
Client object = client.getObject();
if (object == null) {
return new ArrayList<Account>();
} else {
return services.getSortedAccounts(object.getId().toString());
}
}
}
public class ContextsOfAccountModel extends
LoadableDetachableModel<List<ContentType>> {
private WSServicesIF services;
private IModel<Account> account;
public ContextsOfAccountModel(IModel<Account> account, WSServicesIF
services) {
this.account = account;
this.services = services;
}
@Override
protected List<ContentType> load() {
Account object = account.getObject();
if (object == null || object.getId() == null) {
return new ArrayList<ContentType>();
} else {
return services.getContentTypeForAccount(object.getId().toString());
}
}
}
public class SchedulesOfContextModel extends
LoadableDetachableModel<List<Schedule>> {
private WSServicesIF services;
private IModel<ContentType> context;
public SchedulesOfContextModel(IModel<ContentType> context, WSServicesIF
services) {
this.context = context;
this.services = services;
}
@Override
protected List<Schedule> load() {
ContentType object = context.getObject();
if (object == null) {
return new ArrayList<Schedule>();
} else {
return new
ArrayList<Schedule>(services.getSchedulesForContext(object.getId().toString()));
}
}
}
First is the code of a panel with dropdowns and then I pasted models of
choices to show the way I provide options. I can't see the problem, and in
a way is working, but fails following steps I mentioned in my previous mail.
Thanks for helping!
