Hi,
I am tring to implement JpaPermissionStore in seam 2.2.0 GA and getting a Null pointer Exception at line 199 in JpaPermissionStore as roleTargetProperty is null (roleTargetProperty.getName() ) .

somehow no messages from initProperties() as it rey ti initialize all the properties

here is my Role Class

@Entity
public class RolePermission implements Serializable {

    private static final long serialVersionUID = 1L;

    @Id
    @SequenceGenerator(name = "RolePermission", sequenceName = "role_permission_id")
    @GeneratedValue(generator = "RolePermission")
    private Integer id;

    private String recipient;
    private String target;
    private String action;

    public Integer getId() {
        return id;
    }

    public void setId(Integer id) {
        this.id = id;
    }

    @PermissionRole
    public String getRecipient() {
        return recipient;
    }

    public void setRecipient(String recipient) {
        this.recipient = recipient;
    }

    @PermissionTarget
    public String getTarget() {
        return target;
    }

    public void setTarget(String target) {
        this.target = target;
    }

    @PermissionAction
    public String getAction() {
        return action;
    }

    public void setAction(String action) {
        this.action = action;
    }

and I am adding the role class to component.xml as

  <security:jpa-permission-store   role-permission-class="com.mycompany.package.RolePermission"     /> 

and calling the permissions from action like

 
 permissionManager.grantPermission(new Permission(
                            entityManager.find(MyEntity.class, 60),
                            "update", new org.jboss.seam.security.Role(
                                    "EntityEditRole")));
