[jboss-user] [JBoss Seam] - Displaying data with dataTable

[thejavafreak]

How do I display data with dataTable ?

>From my debug page the query is able to fetch one row of data, but why the rowAvailable is false? How do I set it to true? Is this what cause my data is not able to be displayed?

  | 	<f:subview rendered="#{!suppliers.rowAvailable}">
  | 		<h:outputText value="#{messages['nodata']}"/>
  | 	</f:subview>
  | 	
  | 	<f:subview rendered="#{suppliers.rowAvailable}">
  | 	<h:outputText value="#{suppliers}" />
  | 	<h:dataTable id="suppliers" value="#{suppliers}" var="supplier">
  | 		<h:outputText value="#{supplier.name}" />
  | 	</h:dataTable>
  | 	</f:subview>

Have I missed out on something here?

Thanks in advance
