A form field whose presentation and logic can be customized
Custom fields offer the possibility to create Vaadin form fields with customized presentation and logic.
Fields can be composed of standard or custom Vaadin components on the server side. The field logic can either be reused directly for the CustomField or partly overridden for customized behavior.
This also allows the creation of custom editors for sub-objects on forms, including nesting of forms in CustomFields within other forms.
