Required validation of SELECTION and MULTIPLE_SELECTION fails

[danpalmer101]

If you set a FormElement of type SELECTION or MULTIPLE_SELECTION as required, it will always fail validation because FormBuilder.validate() checks the value field on the FormElement but not the optionsSelected field that is set for these types.

if (element.getRequired()) {
    // Should check optionsSelected if element.type == SELECTION or MULTIPLE_SELECTION
    if (element.getValue() == null || element.getValue().length() == 0) {
        isValid = false;
        if (view instanceof EditText) {
            ((EditText) view).setError(element.getErrorMessageOrDefault());
        }
    }
}

Should be solved, but still the EditText error is not visible. Working on that.
