[jboss-user] [JBoss Seam] - Re: Problem with s:selectItems

[jquery@interia.pl]

I've got Seam from CVS then changed xhtml to:


  | <h:selectOneMenu value="#{personHome.countryId}" >
  |     <s:selectItems value="#{personHome.countries}" var="country" label="#{country.name}" />
  |    <s:convertEntity/>
  | </h:selectOneMenu>
  | 
  | 

And then I got NPE

And why is there NPE connected with getting entity id although I set it on 1 (in code above)?

Thanks for any suggestions.
