Comment:
--------------------------------------------------------------
Components that can be used with fieldgroups have a certain interface.
For Vaadin7, it is the Field<> interface
(changed in Vaadin 8 to HasValue<> - Interface
The way vaadin suggests for additional Field components is to use the CustomField-class.
The attached project has some examples for this way.
