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. jquery View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4026894#...
