I cant get the value in my beans to be set using the config CR1 module

I have a stateless bean

@Stateless
public class FeedbackServiceBean implements FeedbackService {
   .....
   
   private String emailRecipient;

   @Inject
   private EmailManager emailManager; 
   
   ......
}

In my seam-beans.xml I have

<service:FeedbackServiceBean>
   <s:modifies/>
               
   <service:emailRecipient>craig@email.com</service:emailRecipient>
</service:FeedbackServiceBean>

When I inject FeedbackService anywhere the emailManager is injected, but emailRecipient is always null.

Can someone let me know what I'm doing wrong?!!

Many thanks

Craig
