Hi fellows,
Last time I asked how to use chain in CompoundPropertyModel with
LoadableDetachableModel, it worked since my page has no form (no submit).
This time, I make another page and try to use the chain again, and hibernate
throws org.hibernate.NonUniqueObjectException when I submit the form.
Caused by: org.hibernate.NonUniqueObjectException: a different object with
the same identifier value was already associated with the session:
[datastore2.model.DataStoreRole#1]
My Panel:
public UserDetail(String id, DataStoreUser user, final Panel prevPanel) {
super(id);
add(new FeedbackPanel("feedback"));
add(new Link("back") {
public void onClick() {
getParent().replaceWith(prevPanel);
}
});
Form form = new Form("form") {
protected void onSubmit() {
DataStoreUser user = (DataStoreUser)this.getModelObject();
try {
getDelegate().saveUser(user);
info("You have saved the user profile: " +
user.getFullname() + ".");
} catch (Exception e) {
e.printStackTrace();
error("Your user profile state is stale (someone has
updated the same user profile while you are on this page). Please press BACK
and come back.");
}
}
};
form.setModel(new CompoundPropertyModel(new
LoadableDataStoreUserModel(getDelegate().getDataStoreUser(user.getId()))));
form.add(new Label("id"));
form.add(new Label("username"));
form.add(new RequiredTextField("firstname"));
form.add(new
TextField("lastname").setConvertEmptyInputStringToNull(false));
form.add(new Label("email"));
form.add(new Palette("roles", new
Model((Serializable)getDelegate().getDataStoreRoles()), new
RoleChoiceRenderer(), 10, true));
add(form);
}
Is LoadableDetachableModel working for form processing? Because it is
working if I only have
form.setModel(new
CompoundPropertyModel(getDelegate().getDataStoreUser(user.getId())));
The reason why i want this loadable since I want to update the page with
"F5" refresh button again if someone has changed the same user in another
computer.
Thank you :)
