Example 1 with StringLengthValidator

use of com.vaadin.flow.data.validator.StringLengthValidator in project flow by vaadin.

the class BinderInstanceFieldTest method bindInstanceFields_bindNotBoundFieldsOnly_customBindingIsNotReplaced.

@Test
public void bindInstanceFields_bindNotBoundFieldsOnly_customBindingIsNotReplaced() {
    BindAllFields form = new BindAllFields();
    Binder<Person> binder = new Binder<>(Person.class);
    TestTextField name = new TestTextField();
    form.firstName = name;
    binder.forField(form.firstName).withValidator(new StringLengthValidator("Name is invalid", 3, 10)).bind("firstName");
    binder.bindInstanceFields(form);
    Person person = new Person();
    String personName = "foo";
    person.setFirstName(personName);
    person.setBirthDate(LocalDate.now());
    binder.setBean(person);
    Assert.assertEquals(person.getFirstName(), form.firstName.getValue());
    Assert.assertEquals(person.getBirthDate(), form.birthDate.getValue());
    // the instance is not overridden
    Assert.assertEquals(name, form.firstName);
    // Test automatic binding
    form.birthDate.setValue(person.getBirthDate().plusDays(345));
    Assert.assertEquals(form.birthDate.getValue(), person.getBirthDate());
    // Test custom binding
    form.firstName.setValue("aa");
