Hola.

El error de casting que tienes es debido a que cuando ejecutas tu código 
la ventana activa es la ventana de proyecto (ProjectWindow) en lugar de 
una vista como debería ser (View). Para solucionar eso tienes que 
modificar los métodos de la extensión isVisible y isEnabled para que la 
extensión sólo se pueda ejecutar cuando la ventana activa sea una vista.

Un saludo,
Jorge
