  • 0

When I try to load the page the datatable is empty. Using the <h:dataTable ... /> the data shows up in the rows. However after further inspection the list is actually written….but it seems like it uses the toString() of the list directly in the value attribute of the datatable. What is wrong?

Backing bean

@Named
@RequestScoped
public class QuestionTableBacking {

    @Inject
    private QuestionServiceLocal questionService;

    public List<Question> getAllQuestions() {
        return questionService.getAllQuestions();
    }
}

Facelet file

        <h:form>

           <p:dataTable value="#{questionTableBacking.allQuestions}" var="question" >
               <p:column>
                   <h:outputText value="#{question.description}" />
               </p:column>

               <p:column>
                   <h:link outcome="report" value="Rapporter" />
               </p:column>
           </p:dataTable>

        </h:form>

This is what I see in firebug

<p:datatable value="[com.mycompany.myapp.domain.Question@7cf9175c, com.mycompany.myapp.domain.Question@456cd91d, com.mycompany.myapp.domain.Question@6d222286,..... var="question">
               <p:column>
               </p:column>

               <p:column><a href="/myapp/report.faces">Report</a>
               </p:column>
           </p:datatable>

POM file ( they are contained in correct parent elements )

<dependency>
    <groupId>org.primefaces</groupId>
    <artifactId>primefaces</artifactId>
    <version>3.2</version>
    <scope>compile</scope>

    #{question.description} should be turned into String value that is inside the currently iterated question objects .description propety , isn’t that what you see in the output? if that the case , then its all fine…

    EDIT

    after looking at your question update it seems that you haven’t added primefaces jar to your project…

    have you added xmlns:p=”http://primefaces.org/ui to your xhtml file?
