passwordField

passwordField defines a field for entering passwords. Characters typed into this field are masked by default.

For the login page, consider using a dedicated loginForm component that prompts a user password as a part of the authentication process.

  • XML element: passwordField

  • Java class: JmixPasswordField

Basics

The set of attributes of passwordField is similar to textField except there is no datatype attribute. The input for passwordField can only be of type String.

Basic passwordField example:

<passwordField id="passwordField"
               label="New password"
               required="true"
               clearButtonVisible="true"
               helperText="Make it strong!"/>
<button id="createPasswordButton"
        text="Create"/>
@ViewComponent
protected JmixPasswordField passwordField;
@Autowired
protected Notifications notifications;

@Subscribe("createPasswordButton")
protected void onButtonClick(ClickEvent<Button> event) {
    if (passwordField.getValue().isEmpty() == false)
        notifications.create("Password created")
                .show();
    }

Vaadin

Determines whether to prevent entering individual characters that don’t match the regular expression in the setAllowedCharPattern() method. Set to true to restrict invalid characters. Set to false to ignore the restriction.

If the value cannot be parsed to String, the default conversion error message appears.

Handlers

AttachEvent - BlurEvent - ChangeEvent - ComponentValueChangeEvent - CompositionEndEvent - CompositionStartEvent - CompositionUpdateEvent - DetachEvent - FocusEvent - InputEvent - InvalidChangeEvent - KeyDownEvent - KeyPressEvent - KeyUpEvent - validator

To generate a handler stub in Jmix Studio, use the Handlers tab of the Jmix UI inspector panel or the Generate Handler action available in the top panel of the view class and through the Code → Generate menu (Alt+Insert / Cmd+N).

ChangeEvent

com.vaadin.flow.component.textfield.GeneratedVaadinTextField.ChangeEvent corresponds to the change DOM event.

InvalidChangeEvent

com.vaadin.flow.component.textfield.GeneratedVaadinTextField.InvalidChangeEvent is sent when the value of the invalid attribute of the component changes.

validator

Adds a validator instance to the component. The validator must throw ValidationException if the value is not valid.

@Install(to = "passwordField", subject = "validator")
private void passwordFieldValidator(String value) {
    if (value != null && String.valueOf(value).length() < 8)
        throw new ValidationException("Password must be at least 8 characters long");
}
