Clases como parámetros y métodos en el composite
Clases como parámetros y métodos en el composite
Invocando métodos definidos en la interface.
A veces necesitamos pasar solo el nombre del controller o el entity a un composite y desde el invocar a métodos específicos que no serán pasados como parámetros.
Definimos los atributos
controller
Si el método necesita leer atributos lo podemos pasar mediante <f:attribute>
en esos métodos los obtenemos
<composite:attribute name="controller" type="java.lang.Object"/>
<composite:attribute name="next" default="next" />definición del action
action="#{cc.attrs.controller[cc.attrs.next]}"Componente paginator

pages="#{rolController.pages}"

/>La implementacion anterior usaba todos estos parámetros.
se necesitaban pasar los métodos firts, back, next,last, printAll,clear
No es necesario se invocan automáticamente desde el componente paginator
<jmoordbjsf:paginator
rowPage="#{rolController.rowPage}"
clear="#{rolController.clear()}"

printAll="#{rolController.printAll()}"
/>CONTROLLER
Se elminaron los metodos
firts
next

Estos tiene el codigo para controlar el desplazamiento entre las paginas.
