Hi,
ich bin gerade dabei eine Kontaktverwaltung zu Programmieren und nutze als Framework JavaFX. Allerdings werden in der Tableview nicht alle Inhalte angezeigt. Die Inhalte der Spalten ID, Hausnummer, E-Mail und Telefonnummer nicht angezeigt. Die Daten kommen dabei aus einer Datenbank und werden in Objekten der statischen Klasse Person gespeichert.
Hier mein Code:
Ich habe die Arrays welche die ObservableArrayList befüllen überprüft, dort stehen die richtigen werte drin. Aber warum werden sie nicht angezeigt?
