i’m using prettyfaces 3.3.2 and JSF 2.2.1. i want to convert pretty url string to entity object and use the object in the web page. pretty-config.xml:
<url-mapping id="country">
<pattern value="/country/#{countryBean.selectedCountry}">
<convert param="#{countryBean.selectedCountry}" converterId="countryConverter" converterClass="Test.CountryBean" />
</pattern>
<view-id value="/faces/countries/country.xhtml" />
</url-mapping>
country.xhtml:
<f:metadata>
<f:viewParam name="country" value="#{countryBean.selectedCountry}">
<f:converter converterId="countryConverter" />
</f:viewParam>
</f:metadata>
<ui:define name="content">
#{countryBean.selectedCountry.country}
</ui:define>
CountryConverter:
public static EntityCountry country = new EntityCountry();
EntityManagerFactory emf = Persistence.createEntityManagerFactory("testPU");
public EntityCountry getAsObject(FacesContext context, UIComponent component, String value) {
EntityManager em = emf.createEntityManager();
Query query = em.createQuery("SELECT c FROM EntityCountry c WHERE c.url = :countryUrl")
.setParameter("countryUrl", value);
country = (EntityCountry) query.getSingleResult();
return country;
}
public String getAsString(FacesContext context, UIComponent component, Object value) {
EntityCountry c = (EntityCountry) value;
return c.getUrl();
}
i toggle breakpoint to getAsObject method but it does not hit the breakpoint. faces-config.xml:
<converter>
<converter-id>countryConverter</converter-id>
<converter-class>Test.CountryConverter</converter-class>
</converter>
<managed-bean>
<managed-bean-name>countryBean</managed-bean-name>
<managed-bean-class>Test.CountryBean</managed-bean-class>
<managed-bean-scope>session</managed-bean-scope>
</managed-bean>
CountryBean:
@Named("countryBean")
@SessionScoped
public class CountryBean implements Serializable {
private EntityCountry selectedCountry;
public EntityCountry getSelectedCountry() { return selectedCountry; }
public void setSelectedCountry(EntityCountry newValue) { selectedCountry = newValue; }
}
And error:
PrettyFaces: Exception occurred while processing <country:#{countryBean.selectedCountry}> for URL </country/turkiye>

It looks like you are using both PrettyFaces injection and ViewParams. If you are using ViewParams, you should use named parameters instead of parameter injection from PrettyFaces, like this:
Then you can let JSF do the work of converting the value as you have asked it to do so in .
