Form id is corret, but remember that form and feedback panel are not
added directly to modal window. They are inside ConnexionContentPanel
which in turn is added to modalwindow.
In your test you should be able to access form calling getContent()
before get("loginForm"), i.e:
modalWindow.getContent().get("loginForm")
this is the code to construct modal window
final ModalWindowE4N modalConnexion = new
ModalWindowE4N("modalConnexion");
modalConnexion.setTitle("Connexion à l'espace membre");
modalConnexion.setContent(new
ConnexionContentPanel(modalConnexion.getContentId()));
add(modalConnexion);
Form is added in ConnexionContentPanel :
public ConnexionContentPanel(String id) {
super(id);
//Création du formulaire dont les champs seront liés aux champs d'un
membre grace au model
Form<Membre> loginForm = new Form<Membre>("loginForm",
new CompoundPropertyModel<Membre>(new
LoadableDetachableModel<Membre>() {
@Override
protected Membre load() {
return new Membre();
}
}));
//Création et ajout des champs id et pwd au formulaire
TextField<Membre> idField = new TextField<Membre>("membreId");
idField.setRequired(true);
loginForm.add(idField);
PasswordTextField pwdField = new PasswordTextField("password");
pwdField.setRequired(true);
loginForm.add(pwdField);
//Ajout d'un du feedback panel qui contiendra les erreurs relevées
par le formulaire
final FeedbackPanel feedBackPanel = new FeedbackPanel("errorMsg");
feedBackPanel.setOutputMarkupId(true);
add(feedBackPanel);
//création du bouton ajax pour soumettre le formulaire
AjaxButton submitbutton = new AjaxButton("ajaxSubmitLogin") {
@Override
protected void onSubmit(AjaxRequestTarget target, Form<?> form)
{
Membre modelObject = (Membre) form.getModelObject();
Membre membre;
membre = serviceIdentif.identifier(modelObject.getId(),
modelObject.getPassword());
if(membre == null)
error("Identifiant ou mot de passe incorrect");
else
setResponsePage(TableauBordPage.class);
}
@Override
protected void onError(AjaxRequestTarget target, Form<?> form) {
target.addComponent(feedBackPanel);
}
};
loginForm.add(submitbutton);
//ajout du formulaire au panel
add(loginForm);
}
you can see that form id is correct.
It is the same problem with FeedBackPanel errorMsg : I get a null pointer
when I try to get it with modalWindow.get("errorMsg");
