*/
protected boolean checkRequired(FormComponent<?> formComponent) {
final String input = formComponent.getInput();
// when null, check whether this is natural for that component, or
// whether - as is the case with text fields - this can only happen
// when the component was disabled
if (input == null && !formComponent.isInputNullable() && !formComponent.isEnabledInHierarchy())
{
// this value must have come from a disabled field
// do not perform validation
return true;
}
// peform validation by looking whether the value is null or empty
return !Strings.isEmpty(input);
