Bidirectional binding with conversion

OK, so is this the design?
============================================================
The class javafx.beans.binding.Bindings will get three new methods:
public static void bindBidirectional(Property<String> stringProperty, Property<?> otherProperty, Format format);
public static <T> void bindBidirectional(Property<String> stringProperty, Property<T> otherProperty, StringConverter<T> converter);
public static void unbindBidirectional(Object property1, Object property2);
The class javafx.beans.property.StringProperty will also get three new methods:
public void bindBidirectional(Property<?> other, Format format);
public <T> void bindBidirectional(Property<T> other, StringConverter<T> converter);
public void unbindBidirectional(Object other);
If parsing the StringProperty fails, the other property will be set to the default value. If formatting the arbitraty property fails, the StringProperty will be set to the empty String.
============================================================
Sounds good to me!

(Hopefully I got the generics on the StringConverter variant correct)
