Rich User Interfaces

Because a form component could contain any kind of components, the rich user interfaces could be implemented independent of the existent servlets. For example, you could listen to the onOpen event and fulfill a tab panel as illustrated in the previous sections. Yet another example, you could dynamically add more rows to a grid control, where each row might control input boxes with the name property. Once user submits the form, the most updated content will be posted to the servlet.
