  Bindings.bindBidirectional (asset  property1, property & lt; t & gt; property2, the function & lt; s, t & gt; ; Mapping;   
 can make a good addition to the API, even in this case, because the inverseMapping of the function  ToggleGroup  's  selectedProperty  is read only (since each  toggle ' s  set select (...)  The law applies, as well as  ToggleGroup   selectedP Roperty ).  
 The use of some listeners in this case is the way to go.  
 The closest thing to "custom bidirectional map" is that  
  Bindings.bindBiDirectional (StringProperty stringProperty, ObjectProperty & lt; t & gt; otherProperty, StringConverter & lt; t & Gt; converter)   
 method. S & gt; Where a (writeable)
