JSF submitButton that renders on datatable - ajax

Question

This is my JSF(2.2) page :
<h:form>
<p>
Hiker-name
</p>
<p>
<h:selectOneMenu id="smenu">
<f:ajax render="hikerActivities"/>
<c:forEach items="#{hikerPresenter.hikers}" var="hiker">
<f:selectItem itemValue="#{hiker.hikerId}" itemLabel="#{hiker.hikerName}"/>
</c:forEach>
</h:selectOneMenu>
<h:commandButton id="submitHiker" value="Submit" action="#{hikerPresenter.getHikerActivities(hiker.hikerId)}">
<f:ajax execute="smenu" render="hikerActivities"/>
</h:commandButton>
</p>
<p>
<h:dataTable id="hikerActivities" var="hikerActivity" border="1">
<h:column>
<f:facet name="header" >Trip-date</f:facet>
#{hikerActivity.tripDate}
</h:column>
<h:column>
<f:facet name="header">Trip-fare</f:facet>
#{hikerActivity.tripFare}
</h:column>
<h:column>
<f:facet name="header">Trip-duration</f:facet>
#{hikerActivity.tripDuration}
</h:column>
</h:dataTable>
</p>
I want that with a click on the command button, my MBean's method get called with the hikerId from the selected item and gets render on the datatable.
this is my MBean :
#ManagedBean
#RequestScoped
public class HikerPresenter {
#EJB
private HikerControllerLocal hikerController;
public HikerPresenter() {
}
public List<HikerAccessDTO> getHikers(){
return hikerController.getHikers();
}
public List<HikerActivityDTO> getHikerActivities(long hikerId){
System.out.println("Get Hiker Activities Called");
List<HikerActivityDTO> l = new ArrayList();
l.add(new HikerActivityDTO(new Date(1417150800000L), "Montréal", "Valleyfield", "Amine", 22, 45));
l.add(new HikerActivityDTO(new Date(1417160800000L), "Montréal", "Québec", "Farida", 33, 44));
l.add(new HikerActivityDTO(new Date(1417170800000L), "Montréal", "Alloha", "dsdsd", 12, 2332));
return l;
}
}
I suppose that I call the MBean method getHikerActivities on the wrong place because it doesn't even System.out.
What am-I doing wrong?

Answer 1

1:
use f:selectItems instead of f:selectItem
2:
your table missed the value attribute like value="hikerPresenter.hikers"
3:
You must set the value attribute of h:selectOneMenu to set hikerId into the bean, so its not necessary to send it as parameter in the method getHikerActivities
