JSF: h:datatable problem

Question

Hi! I have problem with h:datatable tag in JSF. I don't know, why my datatable is not showing on my page. Some advices?

Here is my code:

<h:dataTable  rows="2" var="deb" value="#{debCredTab.rows}">
                    <h:column>
                        <f:facet name="header">
                            Debet
                        </f:facet>
                        <h:inputText value="#{deb.debet}" />
                    </h:column>
                    <h:column>
                        <f:facet name="header">
                            Credit
                        </f:facet>
                        <h:inputText value="#{deb.credit}" />
                    </h:column>
                    <h:column>
                        <f:facet name="header">
                            DebCredSum
                        </f:facet>
                        <h:inputText value="#{deb.debetCreditSum}" />
                    </h:column>
                </h:dataTable>

And here is my output:

<table rules="all">
  <tbody>
  </tbody>
</table>

The question is: why? I forgot something? Why my table is not showing on the page?

Answer 1

I would test to make sure your rows is not returning null:

<h:outputText value="#{debCredTab.rows eq null}" />

I would then check to see if the number of rows is zero.
