problema chiamata metodo

[nala84]

Ciao a tutti!!
Ho un problema....
Ho 2 pannelli:
1) Bottoni contenente delle JText field e dei bottoni (classe Bottoni)
2) Tabella contenente una tabella che visualizza dei dati presenti nel mio dataBase. (Classe Tabella)

I due Pannelli sn richiamati e aggiunti in un JFrame.

Fin qui nessun problema!!!

Poi, ho creato una classe RowListener che dovrebbe selezionare la riga della tabella e caricare il contenuto nelle JTextField presenti nel pannello Bottoni.

Preciso che il problema dovrebbe essere nel modo in cui vado a richiamare il metodo. Perchè mettendo i pannelli e i metodi nella stessa classe funziona tutto perfettamente!!

:master: Penso di aver detto tutto... Vi posto il codice:

        	Bottoni b = new Bottoni();
        	int row = tabel.t.getSelectedRow();
		
        	System.out.println("hai selezionato la riga:" + row);
			
			b.id.setText ((String) tabel.t.getValueAt (row,0));
