h:DataTable problem

[vwiencek]

Hi,
I'm new to Jboss and web Applications, but I've practiced Java for a long time.
I'm now using seam, and I discover each day more fantastic functionnalities. But I'm faced to a minor (I'm sure) problem :

I'm using a DataTable in a xhtml view, and the column header is repeated at every rows. The code i'm using is :
<h:dataTable
id="persons"
value="#{listPerson}"
var="p" >
<h:column>
<f:facet name="header">
<h:outputText value="FirstName : "/>
</f:facet>
<h:outputText value="#{p.firstName}"/>
</h:column>
</h:dataTable>

Is there something special to do to enable the "header function" of the facet ?

Thanks for your help.
Vincent

Sorry for this post, i just found the solution :
it was a dirty xmlns definition, due to ui inclusions and templates.
