JSF Web Application Wildfly 10 Unknown entity

[marcusdidiusfalco]

Hello,

I am trying to build a simple JSF application which saves data entered by the user

I inject a bean which has been instantiated by a jsf page into a controller and try to persist it from the controller.

I get a

2018-03-14 13:41:04,129 ERROR [org.jboss.as.ejb3.invocation] (default task-13) WFLYEJB0034: EJB Invocation failed on component NewsletterDAOBean for method public java.lang.Object de.rupp.persistence.AbstractDAOBean.save(java.lang.Object): javax.ejb.EJBException: java.lang.IllegalArgumentException: Unknown entity: de.rupp.newsletter.NewsletterData$Proxy$_$$_WeldClientProxy

@FlowScoped("newsletter")
@Named
@Entity
public class NewsletterData implements Serializable {
    
    @Id
    @GeneratedValue
    private Long id;
    private String email;
    private boolean agbChecked;
    
    public String getEmail() {
        return email;
    }
    public void setEmail(String email) {
        this.email = email;
    }
    public boolean isAgbChecked() {
        return agbChecked;
    }
    public void setAgbChecked(boolean agbChecked) {
        this.agbChecked = agbChecked;
    }
    @Override
    public String toString() {
        return "NewsletterData [id=" + id + ", email=" + email + ", agbChecked=" + agbChecked + "]";
    }
    
    

}

@Dependent
@Named
public class NewsletterController implements Serializable {
    
    @Inject
    private NewsletterData newsletterData;
    
    @Inject
    private NewsletterDAOBean newsletterDAOBean;
    
    
    public String checkAGBs() {
        if (this.newsletterData.isAgbChecked()) {
            System.out.println(this.newsletterData);
            newsletterDAOBean.save(this.newsletterData);
            return "lastPage";
        }
        FacesContext.getCurrentInstance().addMessage(null, new FacesMessage("Bitte akzeptieren Sie die AGBs"));
        return null;
    }
}

System.out.println(this.newsletterData);

-> NewsletterData [id=null, email=[e-mail], agbChecked=true]

My persistence DAO works. I have written an Arquillian Test which saves a new NewsletterData.

I use em.persist

Any ideas would be greatly appreciated.
