@thomasnield for the second time I failed to choose suitable braces ... selectedProperty().toObservable().subscribe{signalController.filterSwitchSubject} instead of selectedProperty().toObservable().subscribe(signalController.filterSwitchSubject). Which is syntactically close but crucial with regard to emitting events or not.

[thomasnield]

Ouch, be careful. The nuance of rounded versus curly is silent but deadly.

[zealous]

Can you point me to some reading material about the nuances of the two flavors.

[thomasnield]

@zealous one is a functional parameter, while the other is a plain parameter.

[thomasnield]

The subscribe { } will execute that lambda for each onNext(), while .subscribe(mySubject) will subscribe the Subject as an Observer.

[thomasnield]

So putting a subscribe { mySubject } is basically going to do nothing, other than call a reference to the Subject and do nothing to it.

[zealous]

What do you mean by 'call a reference to the Subject'?
