com.google.gwt.editor.client.adapters.OptionalFieldEditor<T,E>
Type Parameters:
T - The type of data being managed
E - The type of Editor

This adapter can be used when a type being edited has an optional field that may be nullified or reassigned as part of the editing process. This consumer of this adapter will typically expose it via the IsEditor interface: 
 class FooSelector extends Composite implements IsEditor<OptionalFieldEditor<Foo, FooEditor>> {
   private OptionalFieldEditor<Foo, FooEditor> editor = OptionalFieldEditor.of(new FooEditor());
   public OptionalFieldEditor<Foo, FooEditor> asEditor() {
     return editor;
   }
 }
