hopla migos:
mi problema es que no puedo mostrar un jpanel que contiene controles al llamarlo desde un boton, me sale este error. este jpanel que intento mostrar esta dentro de otro jpanel llamado jpanel1 que tiene un CardLayout. aki el codigo del boton.
private void jButton2ActionPerformed(java.awt.event.ActionEvent evt) {
CardLayout card;
card=(CardLayout)this.jPanel1.getLayout();
card.show(panel2,"form2");
}
espero puedan ayudarme, ah estoy utilizando el netbeans 7.1. gracias de antemano
