I'm having problems in getting started with GWT Validation. I just want to
validate some form fields on a page.
I started like this, but don't know how to go on:
class Person {
@Size(min = 4, message = "Name too short.")
private String name;
Person(name) {
this.name = name;
}
}
class MyForm {
@UiField
TextBox name;
@UiHandler
void onClick("saveButton") {
new Person(name);
//...
}
}
What do I have to do in order to validate the field now, and show the error
message from the annotation on the page?
