h:commandLink didn't work in dataTable

In a h:form, the commanLink action work fine and execute my transition.

When my commandLink is in a h:dataTable, it doesn't work

<h:dataTable id="tableReport" value="#

" var="cr" rows="0" >
<f:facet name="header" >
<h:outputText value="Vous avez #

comptes-rendus non édités" />
</f:facet>
<h:colum >
.......
<h:column id="compostage">
<f:facet name="header">Compostage</f:facet>
<h:commandLink id="linkVoirDetail" value="voir" action="voirDetail" />
......

The fallowing example work fine :

<h: form>
<h:commandLink id="linkVoirDetail" value="voir" action="voirDetail" />
</h:form>

Thanks a lot
