This could cause a NullPointerException when the root node is always the same instance (in fxml case with the same retrieved node) and the model is attached/detached multiple times in the view.

Here is a simple project that reproduce the problem. Just select/unselect the checkbox multiple times to reproduce :

What happened ?

    1. When the button is detached from its parent release() will be called
    1. When the button is re-attached from the same parent the the listener will be added again. It will cause the parent property to have two attached listeners
    1. The button is detached again, then the two-listeners will be called. The first one will set the localFacade to null, it will result as a NullPointerException in the second.

I'll send you a pull request in few minutes.
