java - How to bind a JavaFX Label to the selected item from a ListView -


i have listview full of pojos , want label in gui display informations selected item.

my pojo looks that:

class customer {   private string name;   ...   public string getname() {   return name;    }

now when user selects customer list want name of selected customer displayed in label.

obviously can't bind name directly because not property. (and don't want replace customers strings stringproperty-objects because simplestringproperty not serializable , need customer transfered via rmi.)

i've tried beanpathadapter jfxtras (which looks nice way) this: 

    beanpathadapter<multipleselectionmodel> customerbeanpathadapter;     customerbeanpathadapter = new beanpathadapter<>(lstcustomers.getselectionmodel());     customerbeanpathadapter.bindbidirectional("selecteditem.name", lblcustomername.textproperty());

but solution throws me exception:

so hoped there better solution use lstcustomers.getselectionmodel().selecteditemproperty().addlistener(...) , handle population of labels there manually.

a better solution think, 1 gave before, use beanpathadapter tried.
beanpathadapter needs have following property added it:

private final objectproperty<b>  beanprop = new simpleobjectproperty<>(); {     beanprop.addlistener( new changelistener<b>()     {         @override         public void changed( observablevalue<? extends b> ob, b oldval, b newval )         {             setbean( newval );         }     } ); }  public objectproperty<b> beanproperty() {     return beanprop;  }

then in code need following:

beanpathadapter<customer>  custbean; custbean = new beanpathadapter<>( new customer() );   // empty or customer custbean.bindbidirectional( "name", label.textproperty() ); custbean.beanproperty().bind( listview.getselectionmodel().selecteditemproperty() );
