@hudsonb Yes, that did the trick, thanks. This solved the problem (for initial example in Java):

import tornadofx.*
class MyClass {
  var myObservableProperty = SimpleStringProperty()
  var myObservable by myObservableProperty
}

and

val myClass = MyClass()
val property = myClass.myObservableProperty
myClass.myObservable = "New data"
println(myClass.myObservable)

Yeah, I love Kotlin 😃

If you don't need a direct reference to the

SimpleStringProperty

, you can just initialize it as the delegate directly

class MyClass {
   var myObservable by SimpleStringProperty()
}

Good to know, i.e. here I'm getting observable property in one line. But I was using reference to

SimpleStringProperty

to set up observer via

setCellValueFactory
