<s:selectItems> confused by binding objects
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,
jquery
