    <s:selectItems>  confused by binding objects

    Christopher no Newbie

      I have a problem with updating objects from forms containing <s:selectItems>. My scenario is following. After having been logged I display data of logged person taking them from my database:


      @Name("personHome")
      public class PersonHome extends EntityHome<Person> {
      
       @In(create = true)
       CountryHome countryHome;
      
       public void setLoggedPersonInstance(){
       Person person = new Person();
       person = (Person) entityManager.createQuery("select p from Person p where p.login = :login").setParameter("login", Identity.instance().getUsername()).getSingleResult();
       setInstance(person);
       }
       ........
      }
      


      Then I hit the change button

       <div class="actionButtons">
       <s:button id="change"
       value="#{messages.change}"
       view="/specialist/spec_edit_personal_data.xhtml"
       styleClass="button"/>
      </div>
      
      


      and I get editable form with data of logged person. It contains <s:selectItems> with countries.
      Although during displaying this form I get info:


      [RendererUtils] Unable to find component 'country' (calling findComponent on component 'person:_id33'). We'll try to return a guessed client-id anyways - this will be a problem if you put the referenced component into a different naming-container. If this is the case, you can always use the full client-id.
      
      


      the <s:selectItems> is set to the country the logged person comes from.
      
       <h:outputLabel for="country">
       <h:outputText value="#{messages.country}"/>
       </h:outputLabel>
       <s:decorate id="countryDecoration">
       <h:selectOneMenu value="#{personHome.instance.country}" >
       <s:selectItems value="#{countryList.resultList}" var="country" label="#{country.name}" />
       <s:convertEntity/>
       </h:selectOneMenu>
       </s:decorate>
      
      


      If I change country from the list and call update method
      <h:commandButton id="update"
       value="#{messages.update}"
       action="#{personHome.update}"
       styleClass="button"/>
      
      

      then the Person is updated. But if I DON'T change the country and call update method I got exception

      I don't understand why if I don't change the country from the <s:selectItems> the update method will throw exception connected with unknown Entity. How is it connected with binding objects? Could anybody suggest what's going wrong?

      Thanks in advance for help.

      Best regards,
