[jboss-user] [JBoss Seam] - JPDL + EL

Tuesday, 5 December 2006

Hello.

I have some problems with EL in a JPDL file. I am trying to use EL in an action inside my
Process Definition file, but it doesn't work:

JPDL:

  | <?xml version="1.0" encoding="UTF-8"?>
  | 
  | <process-definition
  |   xmlns=""  name="estadosProcess">
  |    <start-state name="Disponible">
  |       <transition name="cambiarEstado" to="Elegir estado"
/>
  |    </start-state>
  |    <decision name="Elegir estado"
expression="#{decidirEstado.estadoInicial}">
  |       <transition name="prestado" to="Prestado">
  |       	<action
expression="#{actualizarEstadoLibro.actualizar(actualizarEstadoLibro.disponible)}"
/>
  |       </transition>
  |       <transition name="sugerido"
to="Sugerido"></transition>
  |       <transition name="eliminado"
to="Eliminado"></transition>
  |    </decision>
  |    <task-node name="Prestado">
  |    	  <task name="devolver">
  |          <assignment actor-id="#{actor.id}"/>
  |       </task>
  |       <transition name="devuelto"
to="Fin"></transition>
  |    </task-node>
  | 
  |    ....
  | 
  | </process-definition>
  | 

Action:

  | public class ActualizarEstadoLibroImpl implements Serializable,
  | 		ActualizarEstadoLibro {
  | 
  | 	private static final long serialVersionUID = 0L;
  | 	
  | 	private Estados disponible = Estados.DISPONIBLE;
  | 	
  | 	public Estados getDisponible() {
  | 		return disponible;
  | 	}
  | 
  | 	public void actualizar(Estados estado) {
  | 		try {
  | 			System.out.println ("//////////////// Actualizando " +
estado.toString());
  | 		} catch (Exception e) {
  | 			System.out.println(e.getMessage());
  | 		}
  | 	}
  | 
  | 	/**
  | 	 * @see org.fundacion.actions.libro.ActualizarEstadoLibro#destroy()
  | 	 */
  | 	@Remove
  | 	@Destroy
  | 	public void destroy() {
  | 	}
  | }
  |
