[jboss-user] [JBoss Seam] - NullPointerException when using <f:selectItem>

[codest]

Hi,

I'm having a strange problem with the following code:
				
  | <h:selectOneMenu id="anredebox" value="#{personalDataItem.anrede}" >
  | 		<f:selectItem itemValue="#{msgs.interview_anrede_frau}" itemLabel="#{msgs.interview_anrede_frau}"/>
  | 		<f:selectItem itemValue="#{msgs.interview_anrede_herr}" itemLabel="#{msgs.interview_anrede_herr}"/>
  | </h:selectOneMenu>
  | 

Backing Bean (extract):

  | @Entity
  | @Name("personalDataItem")
  | @Scope(SESSION)
  | /**
  |  * Class PersoenlicheDatenItem
  |  */
  | public class PersoenlicheDatenItem extends CategoryItem implements PersoenlicheDatenItemInterface, Serializable {
  | 
  |   //
  |   // Fields
  |   //
  | 
  |   /**
  |    * Anrede "Frau" oder "Herr"
  |    */
  |   @NotNull
  |   private String anrede;
  | 
Of course, there is an interface with appropriate getters and setters.

When I'm submitting the form, I receive the following exception:

I wonder what I'm doing wrong, since I've seen such code in other examples where it seems to work. I'm also using <h:selectOneMenu>s with SelectItems provided by server-sided Beans and those work properly. Isn't it possible to generate selectItems like this?

Thanks for any help in advance!
Regards,
Jörg
