Programmatic JavaFXBuilder w/o JavaFX bean properties

[John McDonnell]

I would love not to have to replicate my POJO's as JavaFx beans, but how
will the Java FX property get updated when a standard POJO doesnt have a
mechanism (that I know of, apart from PropertyChangeSupport??) to listen to
changes made to properties, and update the JavaFX property?

Surely adding something like PCS, would mean that the bean isnt a POJO
anymore??
