 Hi Werner,

a little off topic but it might still be relevant for you.

There is a feature request logged in the JavaFX-Jira[1] which asks for
a type safe way to use Bindings.select. It the comments two libraries
are mentioned which do this (and more) and make selecting on object
hierarchies way easier:

 * EasyBind by Toimas Mikula [2] (who is also on this list)
 * LibFX by me [3]

I would recommend checking them out. I'm happy to answer questions and
I'm sure so is Tomas.

 so long ... Nicolai
