In a facelets page I have the following EL expression
#{meetsShowCtlr.allMeets}
<h:dataTable value="#{meetsShowCtlr.allMeets}" var="meet">
<h:column>
<f:facet name="header">Meet Id</f:facet>
#{meet.id}
</h:column>
<h:column>
<f:facet name="header">Name</f:facet>
#{meet.name1}
</h:column>
</h:dataTable>
<h:outputText value="#{meet.id}"/>
0 and empty string are the default values for number and String
