HI,
i have a little probleme with Many To many and combox with Form.
I have 2 entitys class : User.class and UserRole.class
User.class have :
@ManyToMany
private Set<UserRole> userRoles;My process for edit user, i open page with Grid with all users. When i click into a cell , a windows pop up with formlayaut (All textfiels represente my entity class and one combox box for userRoles)
public class UserForm extends FormLayout {
private MainUi mainUi;
Button save = new Button("Save", this::save);
Button cancel = new Button("Close", this::cancel);
TextField userLogin = new TextField("Login");
TextField userPassword = new TextField("Password");
Label userLoginVersion = new Label("Login Version");
TextField userSecureKey = new TextField("Secure Key");
ComboBox userProvider = new ComboBox("User Provider");
OptionGroup userRoles = new OptionGroup("Roles");
Label userProviderId = new Label("Provider ID");
TextField userGameName = new TextField("Game name");
TextField userFastId = new TextField("Fast id");
DateField userLastConnection = new DateField("Last Connection");
Label userLastIp = new Label("Last Ip");
ComboBox userLanguage = new ComboBox("Language");
ComboBox userCountry = new ComboBox("Country");
DateField created = new DateField("Created Date");
DateField updated = new DateField("Created Date");
BeanItemContainer<UserRole> containerBean = new BeanItemContainer<UserRole>(UserRole.class);
BeanFieldGroup<User> formFieldBindings;
User user;
public UserForm(MainUi mainUi) {
this.mainUi = mainUi;
configureComponents();
buildLayout();
}
private void configureComponents() {
save.setClickShortcut(ShortcutAction.KeyCode.ENTER);
setVisible(true);
updated.setReadOnly(true);
created.setReadOnly(true);
save.setIcon(new ThemeResource("icons/synchronize2.png"));
cancel.setIcon(new ThemeResource("icons/loading2.png"));
userLanguage.addItems(CountryCode.values());
userCountry.addItems(CountryCode.values());
userProvider.addItems(UserProvider.values());
containerBean.addAll(mainUi.userRoleService.getListUserRole());
// userRoles.addItems(mainUi.userRoleService.getListUserRole());
userRoles.setContainerDataSource(containerBean);
userRoles.setMultiSelect(true);
userRoles.setRequired(true);
}
private void buildLayout() {
setSizeUndefined();
setMargin(true);
HorizontalLayout actions = new HorizontalLayout(save, cancel);
HorizontalLayout groupField = new HorizontalLayout(userLogin, userPassword);
HorizontalLayout groupField2 = new HorizontalLayout(userFastId, userGameName);
HorizontalLayout groupField3 = new HorizontalLayout(userSecureKey, userProvider);
HorizontalLayout groupField4 = new HorizontalLayout(userLanguage, userCountry);
HorizontalLayout groupField5 = new HorizontalLayout(created, updated);
actions.setSpacing(true);
addComponents(groupField, groupField2, groupField3, groupField4, userRoles, userProviderId,
userLastConnection, userLastIp, userProviderId, userLoginVersion,
groupField5, actions);
}
private void save(Button.ClickEvent event) {
try {
formFieldBindings.commit();
mainUi.userService.saveUserRole(user);
fireEvent(new DataUpdate(event.getComponent(), DataUpdate.editAction.UPDATE_DATA));
} catch (FieldGroup.CommitException ex) {
fireEvent(new DataUpdate(event.getComponent(), DataUpdate.editAction.CLOSE_EDIT));
}
}
private void cancel(Button.ClickEvent event) {
fireEvent(new DataUpdate(event.getComponent(), DataUpdate.editAction.CLOSE_EDIT));
}
public void edit(User user) {
this.user = user;
if (user == null) {
this.user = new User();
}
formFieldBindings = BeanFieldGroup.bindFieldsBuffered(this.user, this);
//DEBUG
if (user.getId() != null) {
for (UserRole role : containerBean.getItemIds()) {
System.err.println("1 " + role.hashCode());
}
}
for (UserRole role : user.getUserRoles()) {
System.err.println("2 " + role.hashCode());
}
}
}Bind working good for all field and i can save object user with new parameters but ComboBox represente all userRoles by not set active actif user role for edit User.
I Understand where is my probleme , i try to print hascode object to my fonction edit and of exemple :
Systeme out :
: 1
86797355
// USER_ROLE_ADMIN object of my combobox
: 1 1388651512 // USER_ROLE_WEB object of my combobox
: 1 1731178725 // USER_ROLE_TEST object of my combobox
: 2
435341188
// USER_ROLE_ADMIN object of my UserRoles list , hashcode is not same but is same object.
Environement : Glassfish 4.1 - Spring 4.2.2 - Spring security 4.0.3 - Hibernate 4.3.5 - Vaadin 7.5.9
Could you help me ?
Question 2 :
I have other little probleme with TextField Component , i have class with longitude and latitude (GPS pos) double format.
When i click to map add call eventlistener for exemple i print Lat: 51.344338660599234 Lon: -1.4666748046875
[code]
TextField containerLatitude = new TextField(“Latitude”);
…
containerLatitude.setValue(position.getLat()); // Lat is 51.344338660599234
[/code]Textfield cut number and write 51.344 and remove others number.
Coudl you help me ?
