+/**
+    Welcome.
+
+    If you read this documentation, it probably means that you were asked to use a form view widget outside of
+    a form view. Before going further, you must understand that those fields were never really created for
+    that usage. Don't think that this class will hold the answer to all your problems, at best it will allow
+    you to hack the system with more style.
