Hello,
I'm in the need of programmatically accessing (I mean not using @In annotation) a component which is created with @Factory . But neither this:
Course course = (Course)Contexts.lookupInStatefulContexts("course") ;
nor this, is working:
Course course=(Course)Contexts.getSessionContext().get("course") ;Both methods return null, as if the factory method is not been called. Is this correct behavior or could it be something in my code, I reproduce here the related parts.
By the way I'm not able to inject the component because its factory method is declared inside a component with @Restrict("#{identity.loggedIn}") declared, but I'm trying to use it when no login has happened yet. But just before I plan to use the login ocurrs, so at that time the @Restrict should not be a problem. If I try to use @In the injection tries to occur to early.
I think I better wrote the code:
firstly the component with the declared factory
@Name("courseManager")
@Scope(ScopeType.SESSION)
@Restrict("#{identity.loggedIn}")
public class CourseManagerAction implements CourseManager {
@Factory
public Course getCourse() {
// gets default single course
Course course = (Course) entityManager
.createQuery("select c from Course c").getSingleResult();
return course;
}
}
then the case where I want to use the "course" component:
@Scope(ScopeType.EVENT)
@Name("register")
public class RegisterAction implements Register {
public void register() {
//here the user register itself ....
//after that do auto-login
identity.authenticate() ;
//now I want to access the course
Course course = (Course)Contexts.getSessionContext().get("course") ;
//but course is null
//why? shouldn't this call be similar to: @In Course course ??
}
}
any comments?
