Invocar metodos desde un controller

• usados con jmoordbjsf

• muestra todos los métodos de un controller

• invoca un metodo de un controller que se ha pasado

• Creamos una instancia del entity pasado como parametro

Object b = entity.getClass().newInstance();

Invocamos el metodo

userInfoSetter .accept(lcontroller, value);
