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.
