JavaFX binding and null values

Question

I was wondering how to bind values where the source of the bind could be null.

I have a property:

private ObjectProperty operation = new         


        

Answer 1

Just in case if somebody using not Java itself but Kotlin. It is a good idea to use wonderful tornadofx library. There you can just use operation.select{it.name}. Although, this feature seems not to be documented yet, so it took some time to discover it.
