Swing jLabel im Zusammenhang Sockets

[Crackhouse69]

Hallo, erst einmal ein großes Lob an das Forum. Einige Beiträge haben mir hier schon sehr geholfen.

Nun zu meinem Problem:

Ich habe mir eine Client - Server Struktur gebaut.
Der Server sendet Nachrichten zum Client wo Namen drinstehen.
Die Nachrichten werden vom Client ausgewertet und kommen auch an.
Ich hatte mir für die GUI ein plugin für Eclipse runtergeladen namens: Matisse Form.
Die Trial Version ist abgelaufen, aber der Code blieb erhalten.
Die empfangenen Nachrichten enthalten Namen für Laptops die in das jeweilige Jlabel geschrieben werden sollen.
Initial sind die jLabels auf invisible. Wenn die Nachricht ankommt, dass 3 Laptops vorhanden sind, sollen die ersten 3 Labels auf visible gesetzt werden und die jeweiligen Namen reingeschrieben werden.
Als das Plugin noch verfügbar war, hatte alles geklappt, nur jetzt nicht mehr. Der Code blieb der selbe.
Hier erst einmal die Requester - Klasse wo die Nachrichten ausgewertet werden:



und hier die Controller - Klasse wo die Funktion "setgui" aufgerufen wird um die GUI mit den jeweiligen JLabels aktualisiert werden soll:

und noch meine Fenster - Klasse, wo alle GUI Komponenten enthalten sind:



Vielen Dank schon mal für eure Hilfe!

Gruß.
