I have a PrimeFaces datatable. For each
row in this table, I want to allow the user to update/delete the
row entry (a user).

<h:form>
<p:panel id="viewUsersPanel" header="View Users">
<p:dataTable var="user" value="#{uController.users}"
emptyMessage="No Users Found.">
<p:column style="text-align: center;">
<f:facet name="header">
<h:outputText value="Name" />

<h:outputText value="#{user.name}" />
</p:column>
<p:column style="text-align: center;">
<f:facet name="header">

</f:facet>
<h:outputText value="#{user.address}" />
</p:column>
<p:column style="text-align: center;">
<f:facet name="header">
<h:outputText value="Phone Number" />
</f:facet>
<h:outputText value="#{user.phone}" />
</p:column>
<p:column style="text-align: center;">
<f:facet name="header">
<h:outputText value="Email Address" />

<h:outputText value="#{user.email}" />
</p:column>
<p:column style="text-align: center;">
<f:facet name="header">

</f:facet>
<h:outputText value="#{user.dob}">
<f:convertDateTime pattern="dd-MMM-yyyy" />
</h:outputText>
</p:column>
<p:column style="text-align: center;">
<f:facet name="header">
<h:outputText value="No. Memberships" />
</f:facet>
<h:outputText value="#{user.numberOfMemberships}" />
</p:column>
<p:column style="text-align: center;">
<f:facet name="header">
<h:outputText value="Actions" />
</f:facet>
<h:commandButton value="Update" action="#{uController.update}" />
<h:commandButton value="Delete" action="#{uController.delete}" />
</p:column>
</p:dataTable>
<h:panelGrid columns="2" cellpadding="2" id="footerPanelGrid"
border="0">
<h:commandButton action="#{uController.home}" value="Home Page" />
</h:panelGrid>
</p:panel>
</h:form>
</center>
</h:body>
</html>
However, neither of the buttons work. Instead they appear to simply refresh the view page. I have ran the app in debug and neither update or delete method is hit.
I suspect this may be due to using h:commandButton within a p:dataTable. However, I have also tried p:commandButton but to no avail.
For reference, here is a snippet of the UserController class:
@ManagedBean(name="uController")
public class UserController extends AbstractController {
private Collection<User> users;
...
public String update() {
System.out.println("Ready for update");
return "update-user";
}
public String delete() {
System.out.println("Ready for delete");
return "delete-user";
}
...
}
