... aber es geht schon wieder ums JTable. Bin ein ziemlicher noob wenns um Swing geht und das JTable FAQ von Beni hat mir wirklich sehr geholfen (danke für die Arbeit 
. Jedenfalls soll die Applikation einfach Telefonbucheinträge verwalten. Bei der Anzeige hab ich zwei Renderer verwendet weil ich das mal so probieren wollte, einen für die normalen Einträge und einen für die Adresseinträge der die Daten in einer ComboBox darstellt. Mein Problem ist jetzt dass wenn ich eine Reihe selektiere... nur die ComboBox die grüne Farbmarkierung bekommt obwohl ich mit gedacht hätte dass es die restlichen Einträge auch grün werden da auch im LabelRenderer der Hintergrund grün gesetzt wird.
thx
