I tried the combination of JavaFX with CDI and injection of Kotlin and it works very well.
First the CDI - managed Callable
Second the TextFieldBindingCallable for the JavaFX-binding
Third the implementation of the DemoLogic
Java - Version
changed to Kotlin
The code with the @Inject of DemoLogic isn´t changed inside the class LeftTextFieldBindingCallable
and it is running well..
