movieDisplayGroup’s selected
object to the movie the user clicked.
public void selectObject() {
movieDisplayGroup.selectObject(movie);
}
Bindings in the Editing Part

movieDisplayGroup’s selectedObject—the movie on which the user clicked.
Typing new values into these fields updates the Movie enterprise object.
To actually save the updated values to the database, the user must click the
“Save to database” button.
