[Andres Felipe jama]

reciban cordial saludo señores de gvSIG
Trate de montar esa extensión y llamar la  clase AddEventThemeExtension  desde un botón cualquiera de mi extensión, de tal forma que permitiese al usuario desplegar el menú para cargar una tabla en formato csv y se los grafique pero me saco este error..
anexo el código desde el botón del cual trato de llamar LA  clase   AddEventThemeExtension.

  AddEventThemeExtension intento = new AddEventThemeExtension();   intento.execute("String actionCommand");
este error me lo esta mostrando en gvSIG
MUCHAS GRACIAS POR SU AYUDA
