title: Converter for rich:comboBox. What if string representations of enities can contain duplicate elements?
body: <p>For example I have PersonEntity and want to use it in rich:comboBox. I must specify converter for this entity (otherwise toString of PersonEntity will be used). PersonConverter return firstname and lastname - "John Smith" and there can be many persons with same name and surname, so converter's getAsObject method will fail to distinguish them and wrong enity will be choosed.
  So, what should I do?</p>
