Displaying multiple form errors
I am trying to build a form with multiple fields and would like to show all errors when form validation fails. From looking at samples, it looks like we can only have one Form.Flag per box pane such as following snippet from Forms.java
submitButton.getButtonPressListeners().add(new ButtonPressListener() {
@Override
public void buttonPressed(Button button) {
String lastName = lastNameTextInput.getText();
String firstName = firstNameTextInput.getText();
Form.Flag flag = null;
if (lastName.length() == 0
|| firstName.length() == 0) {
flag = new Form.Flag(MessageType.ERROR, "Name is required.");
}
Form.setFlag(nameBoxPane, flag);
if (flag == null) {
errorLabel.setText(null);
Prompt.prompt("Pretending to submit...", window);
} else {
errorLabel.setText("Some required information is missing.");
}
}
});
Is it possible to show error messages next to each field when form validation fails. I would appreciate for any examples. Thanks.

This is potentially doable if we add an orientation property to the Form class. That way, you could nest forms inside of other forms and get the highlight behavior on nested fields. You are welcome to file a feature request in JIRA for this if you like - I'd suggest submitting it for v 2.0.

Thanks, this looks pretty nice. I think I might be able to provide some feedback using listeners, but it would be nice to see support errors per field in future release to reduce boiler plate code.

Messages can also be displayed inline such that they are always visible (i.e. they don't only appear on mouse over). Additionally, the flag icons are now more consistent with their Alert/Prompt equivalents.

Form has no way of knowing that you have multiple text inputs inside the box pane, so it can't attach a flag to those text inputs. It can only show a flag for the fields it knows about.

This is unfortunately not supported. The Form container supports one flag per field (where fields are defined by the form's sections). Form has no way of knowing that you have multiple text inputs inside the box pane, so it can't attach a flag to those text inputs. It can only show a flag for the fields it knows about.
