title: JavaFX ComboBox - How to get different Prompt Text and Selected Item Text?
body: <p>I've searched a bit, but couldn't find an answer. The Combobox is editable. How can I show different text in the Combobox prompt text and in the list of Objects below? In the list I want the toString method of the Object to be used, but when I select it, I want only one attribute of the selected Object to be shown in the prompt text.</p>
  
  <p>How can I do this? Is it possible to display the value of an object differently in the prompt text field and in the list below?</p>
  
  <p>An example of the usage would be with songs. Let's say I search a song by title, then it shows me the song with the title, composer and instrument below. When I select the song, I only want the title to be shown in the prompt text (because I display the composer and instrument Information somewhere else).</p>
