Session is null
Hi all,
I was just wondering if someone could help me out with this. I'm pretty sure that I have set everything up correctly, but whenever I navigate to a certain page, it tells me that my session is null.
Below are the relevant files.
Any help will be most appreciated.
Thanks,
Robert

This is the object that I'm using. EventT is the entity object.
@Name("eventTList")
public class EventTList extends HibernateEntityQuery<EventT> {
private EventT eventT = new EventT();
@Override
public String getEjbql() {
return "select eventT from EventT eventT";
}
@Override
public Integer getMaxResults() {
return 25;
}
public EventT getEventT() {
return eventT;
}
}
Here is the part of the page I'm using this in
<h:form id-="form2">
<rich:dataTable id="eventDataTable"
value="#{eventTList}" var="event">
<h:column>
<h:outputText id="eventName" value="#{event.name}" />
</h:column>
<h:column>
<h:inputHidden id="eventUUID" value="#{event.id}" />
</h:column>
</rich:dataTable>
</h:form>Here is the stack trace that I get, in case it helps at all.
