I'm trying to replicate this guide but with jsf 2.2:
http://www.mkyong.com/jsf2/jsf-2-datatable-example/
My current setup: a class called Message holds a date, string, and an account object called "name" (its owner). A MessageBean class has a List object messageSet, that gets initialized in the MessageBean constructor. A JSF page fills a table with the messageList. However, the table doesn't get filled. When looking at the list object in the debugger, it does get filled with valid message objects. My classes: @Named(value = "messageBean") @SessionScoped public class MessageBean implements Serializable { private List messageSet;
public MessageBean()
{
this.messageSet = Controller.Controller.getLatestKweks();
}
public List<Message> getMessageSet()
{
return messageSet;
}
public void setMessageSet(List<Message> messageSet)
{
this.messageSet = messageSet;
}
}
The JSF page:
<h:dataTable value="#{messageBean.messageSet}" var="mes">
<h:column>
<f:facet name="header">Date</f:facet>
#{mes.mesDate}
</h:column>
<h:column>
<f:facet name="header">Naam</f:facet>
#{mes.name.accountName}
</h:column>
<h:column>
<f:facet name="header">Content</f:facet>
#{mes.Content}
</h:column>
</h:dataTable>
There's a second Message object that is a Hibernate object, only having getters and setters in it.
Here's the stacktrace when I try to access this page:

And the scoped variables:

Anyone have any idea why the table won't fill?
