    duplicate Id for a component...

      Hi,
      Using Seam 1.2.1.GA + JBoss AS 4.0.5.GA, I have a xhtml page with a datatable. The number of columns of this table is variable. I use a jstl <c:foreach> in this datatable like this:

      <h:form id="MyForm">
      ...
      <h:dataTable value="#{bean.var}" var="lineSimple">
       <h:column>
       <f:facet name="header">
       <h:outputText value="Activite" />
       </f:facet>
       <h:outputText value="#{lineSimple.lineDesignation}"/>
       </h:column>
      
      <c:forEach items="#{bean.var.columnDataModel.wrappedData}"
      var="columnSimple">
       <h:column>
       <f:facet name="header"> <h:outputText value="#{columnSimple.columnDesignation}"/>
       </f:facet>
       <h:inputText value="#{lineSimple.cellList[columnSimple.columnId].cellValue}"/>
      ...
      </c:forEach>
      ...
      </h:form>


      All this is in a form with other inputs. My page uses a template with an Ajax menu that is also in a form. When I change the values of my inputs, the number of columns of the table increases. When I do it once it's ok but when I do it again I have this error:
