title: JavaFX: Update of ListView if an element of ObservableList changes
body: <p>I would like to display a list of persons (coded in POJOS, and containing a name and surname property) using a JavaFX ListView control. I created the ListView and added the list of persons as an ObservableList. Everything works fine if I delete or add a new person to the ObservableList, but changes in the POJO do not trigger an update of the ListView. 
  I have to remove and add the modified POJO from the ObservableList to trigger the update of the ListView. 
  Is there any possibility to display changes in POJOS without the workaround described above?</p>
