			<p:dataExporter type="xls" target="dataTable" fileName="listeStructure" excludeColumns="4"/>
		</h:commandLink>

and the datatable is this

Code: Select all

<rich:dataTable style="width : 98% ; align : center"
			binding="#{structureBean.dataTable}" id="dataTable">
			<f:facet name="header">
				<h:outputLabel value="#{i18n.structure_resultat}"></h:outputLabel>
			</f:facet>
			<rich:column id="colcode" sortBy="#{item.codearbo}">
				<f:facet name="header">
					<h:outputLabel value="#{i18n.structure_codeArbo}"></h:outputLabel>
				</f:facet>
				<h:outputText value="#{item.codearbo}" />
			</rich:column>

  <el-resolver>org.springframework.web.jsf.el.SpringBeanFacesELResolver</el-resolver>
  <resource-bundle>
            <base-name>ApplicationMessages</base-name>
            <var>i18n</var>
  </resource-bundle>
  <locale-config>
   <default-locale>fr_FR</default-locale>
   <supported-locale>fr_FR</supported-locale>

  </locale-config>

the solution is to download the latest jar primefaces-1.0.0.RC.jar

primefaces-1.0.0.RC.jar is not latest for sure.
