title: JavaFX: IllegalArgumentException when mouse is clicked any where on scene
body: <p>Hi I am getting <code>IllegalArgumentException</code> when I click on any Control or on empty space of the scene. Below is the stack trace. I cant write a method for each control's <code>MouseEvent</code>. Could you please suggest a solution to cancel this mouse event when I click on empty space in scene or on disabled controls.</p>
