javafx - ChangeListener on multiple Properties

Question

I have a model Tree of different POJOs containing several JavaFX Property<?> properties.

I was now wondering on how to attach a ChangeListener to the top of the tree which is fired every time something in the object tree changes.

I experimented a lot with custom Bindings and Invalidations but I think I am missing something here.

The background here is, that I want to detect if the model needs to be saved or not. And I do not want to attach a change listener to every single property in that tree. There must be a better way.
