Exception when use customsized Converter and Ajax in Seam 3 application.

hantsy Sep 8, 2011 6:50 AM

I used a dropdown box to select country, then render the city selector and area selecter...
But when i selected country, and tried to select city, I got an exception.

The country converter, the city converter is similar with country converter. Converter class is from the Seam 3 faces module.

@FacesConverter("countryConverter")
@RequestScoped
public class CountryConverter extends Converter<Country> {

     @Inject
     EntityManager em;

     @Override
     public Country toObject(UIComponent comp, String value) {
          if (value == null || "".equals(value.trim())) {
               return null;
          }
          return em.find(Country.class, Long.valueOf(value));
     }

     @Override
     public String toString(UIComponent comp, Country value) {
          if (value == null) {
               return "";
          }
          return value.getId().toString();
     }

}

the partial page code.

                              <p:input id="addressCountry"
                                   label="#{messages['Addressee.Country']}">
                                   <h:selectOneMenu id="input"

                                        <f:selectItems var="counVar" itemLabel="#{counVar.name}"

                                        <a4j:ajax event="change" render="cityPortSelector"
                                             execute="@this" />
                                   </h:selectOneMenu>
                              </p:input>
                              <a4j:outputPanel id="cityPortSelector">
                                   <ui:fragment rendered="#{addresseeEdit.selectedCountry ne null}">
                                        <p:input id="city" label="#{messages['Addressee.City']}">
                                             <h:selectOneMenu id="input"
                                                  value="#{addresseeEdit.currentAddressee.city}">
                                                  <f:selectItems var="cVar" itemLabel="#{cVar.name}"
                                                       value="#{addresseeEdit.cities}" />

                                             </h:selectOneMenu>
                                        </p:input>

How to overcome the barrier?

Any help is appreciated.

I had the same issue before and changed the Mojarra version back to 2.0.3-b05. Now ajax works fine as it should.

Try to drop jsf-impl-2.0.3-b05.jar here:
/your/path/jboss-as-web-7.0.1.Final/modules/com/sun/jsf-impl/main

and modify module.xml:

<module xmlns="urn:jboss:module:1.0" name="com.sun.jsf-impl">
    <dependencies>
        <module name="javax.faces.api"/>
        <module name="javaee.api"/>
        <module name="javax.servlet.jstl.api"/>
        <module name="org.apache.xerces" services="import"/>
        <module name="org.apache.xalan" services="import"/>
    </dependencies>

    <resources>

I replaced it with 2.0.6 FCS, but got the same exception.
I must use 2.0.3-b05?

I think yes. At least 2.0.3-b05 is the only working version for me.

I think the ajax bug is fixed in the current version, but that one doesn't invoke s:viewAction methods.

Ah sorry fail I'm using Mojarra 2.0.2 (FCS b10). Please try this version.

Here is an example:

<components:input id="search-dec-brand"
     labelText="#{bundles.messages['inseration.refinesearch.Brand']}"
     labelStyle="width: 55px" useSpacer="true">
     <h:selectOneMenu id="search-brand"
          value="#{inserationAgent.brand}" style="width: 200px">
          <f:selectItem
               itemLabel="#{bundles.messages['inseration.refinesearch.Select']}"
               itemValue="#{null}" />
          <f:selectItems value="#{inserationAgent.brands}" var="brand"
               itemLabel="#{brand.name}" itemValue="#{brand}" />
          <a4j:ajax event="change"
               render="searchForm_results_resultPanel" execute="@this"
               listener="#{inserationAgent.find}" />
          <f:converter converterId="inserationBrandConverter" />
     </h:selectOneMenu>
</components:input>

As you see here. AJAX works awesome.

You are welcome.

Your website looks very good.

But our before project is based on Seam2.2 and richfaces 3.3, the generated html by richfaces is very terrible, we used many rich components, such as toolbar, extendedDataTable, tree, drag and drop, context menu...so the cusotmer did not satisfy the page performance.

Different from ur website, we have many complex insert and update operations, this is an internal web system, not a website.

I have been doing some research on Seam 3 in these two weeks, if I can not overcome the barriers I encountered in these days, I think we will keep on Seam 2...and replace the rich components with plain standard jsf component and pure client solution(HTML and javascript).

Looks to me like that's an error with your application. as you can see in the log it's an INFO from a handler you created. If you want more info try debugging the handler you created and see what the problem is.

I have said, it worked well when use 2.0.2...

I only want to try the newest JBoss 7.0.2Final yesterday, I got the same exception. I do not know it was caused by Richfaces or the compatibility between Glassfish jsf impl and Richfaces.

I will replace the a4j tag with pure jsf ajax tag and have a try.
