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

[jquery@interia.pl]

Actually the difference between parameters in set and get methods appeared because I was trying different combination of collections.
It was my mistake.
Now as you said the I have following code:

  | @Name("personHome")
  | public class PersonHome extends EntityHome<Person> {
  | 
  |             public List<Country> countries = new ArrayList<Country>();
  | 	public long countryId = 1;
  | 	
  | 
  | 	public long getCountryId() {
  | 		return countryId;
  | 	}
  | 
  | 	public void setCountryId(long countryId) {
  | 		this.countryId = countryId;
  | 	}
  | 
  | 	public void setCountries(List<Country> countries) {
  | 
  | 	}
  | 
  | 	public List<Country> getCountries(){
  | 		Country country = new Country();
  | 		country.setId(1);
  | 		country.setName("Poland");
  | 		countries.add(country);
  | 
  | 		return countries;
  | 	}
  | }
  | 

And xhtml:


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

And a converter which is based on ui seam example:


  | 
  | @Name("countryConverter")
  | public class CountryConverter {
  | 	Converter getConverter(){
  | 		return new Converter(){
  | 			 @Transactional
  | 	         public Object getAsObject(FacesContext arg0, UIComponent arg1, String arg2) throws ConverterException
  | 	         {
  | 	            if (arg2 == null) {
  | 	               return null;
  | 	            }
  | 	            try {
  | 	               return  ((EntityManager) Component.getInstance("entityManager")).find(Country.class, Integer.valueOf(arg2));
  | 	            } catch (NumberFormatException e) {
  | 	              throw new ConverterException("Cannot find selected country", e);
  | 	            }
  | 	         }
  | 
  | 	         @Transactional
  | 	         public String getAsString(FacesContext arg0, UIComponent arg1, Object arg2) throws ConverterException
  | 	         {
  | 	           if (arg2 instanceof Country)
  | 	            {
  | 	               Country country = (Country) arg2;
  | 	               return (new Long(country.getId())).toString();
  | 	            }
  | 	           else
  | 	           {
  | 	              return null;
  | 	           }
  | 	         }
  | 
  | 		};
  | 	}
  | 
  | }
  | 

But I still get error:


  | Value is no String (class=java.lang.Long, value=1) and component person:_id38with path: {Component-Path : [Class: org.ajax4jsf.framework.ajax.AjaxViewRoot,ViewId: /specialist/spec_registration.xhtml][Class: javax.faces.component.html.HtmlForm,Id: person][Class: org.jboss.seam.ui.UIValidateAll,Id: _id7][Class: org.jboss.seam.ui.UIDecorate,Id: _id37][Class: javax.faces.component.html.HtmlSelectOneMenu,Id: _id38]} does not have a Converter
  | 
  | 

I don't know where the error comes from and why the converter is not visible.
I would apprecite any suggestions.
