Can�t manage to select a row in a t:dataTable

Question

I use a tomahawk dataTable to list a collection of objects called �dmex� in dmexTable.jsp
When I select one row to edit details in the next page �dmexDetails.jsp� I systematically get the last entries of my table.
In debug mode I could find out that JSF/MyFaces iterates through the whole list instead of selecting only the entry I clicked on.
Here is my code of dmexTable.jsp where #{dmexTable} is a backingBean of dmexTable.jsp and #{dmexBean} the backingBean of dmexDetails.jsp
<h:form id="formDmexTable">
<t:dataTable id="dmexTable"
          cellspacing="3"
          cellpadding="3"
          styleClass="orders"
          headerClass="ordersHeader"
          rowClasses="evenRow,oddrow"
          var="rowDmex"
          value="#{dmexTable.dmexList}"
          preserveDataModel="true" >
<h:column>
<f:facet name="header">
     <h:outputText value="Id" id="columnDmexId" />
     </f:facet>
     <h:outputText value="#{rowDmex.dmexId}" id="rowDmexId" />
</h:column>
<h:column>
<f:facet name="header">
<h:outputText value="#{msgsDmex.application}" id="columnApps" />
</f:facet>
<t:commandLink id="selectDmexApps" action="go_to_dmexDetails" immediate="true">
<h:outputText value="#{rowDmex.application}"
id="rowApplication" />
<t:updateActionListener property="#{dmexBean.dmexId}"
value="#{rowDmex.dmexId}" />
</t:commandLink>
</h:column>
� some others properties in other columns �
</t:dataTable>
</h:form>
Herebelow the code of my RequestScope ManagedBean #{dmexTable} containing a property dmexList and a hibernate Class called �dmexManager� that gives access to the dataBase :
public class DmexTable{
private ArrayList dmexList ;
private bsa.integration.service.DmexManager dmexManager;
public ArrayList getDmexList() {
dmexList = (ArrayList) dmexManager.findPoolList(new Dmex())
return dmexList;
public void setDmexList(ArrayList dmexList) {
     this.dmexList = dmexList;
SOFAR EVRYTHING WORKS FINE ; I can list my dmex in the dataTable dmexTable !
Here below is the code of my JSP view called �dmexDetails.jsp� where #{dmexBean}is still the backingBean of the view :
<h:form id="formDmexIdentification">
<t:saveState value="#{dmexBean.dmexId}" />
<h:panelGrid columns="2">
<h:outputText value="id" styleClass="sorti" />
     <h:outputText value="#{dmexBean.dmex.dmexId}"styleClass="sorti"/>
     <h:outputText value="#{msgsDmex.application}" styleClass="sorti" />
<h:inputText value="#{dmexBean.dmex.application}"
size="6" styleClass="ent" required="true" id="inputApplication" />
<h:message for="inputApplication" styleClass="mess" />
Herebelow the code of my RequestScope ManagedBean #{dmexDetails} containing the �t:saveState� property dmexId and the hibernate Class �dmexManager� that gives access to the dataBase :
public class DmexBean {
private int dmexId ;
public int getDmexId() {
     return dmexId;
// this is the method that JSF/MyFaces iterates through when clicking on one commandLink of the Table !!!
public void setDmexId(int _rowDmexId) {
if (_rowDmexId > 0)
dmex = getSimpleDmex(_rowDmexId);
if (dmex == null) {
return;
private Dmex getSimpleDmex(int _id) {
dmex = (Dmex)dmexManager.findOneId(new Dmex(),_id);
return dmex;
I can�t figure out why clicking on the command Link JSF/MyFaces does not simply send back the selected dmexId !
May someone give a hint ? I have nomore Idea since my implementation seems exactly similar to the MyFace example I used ..

Hello !
Okay, I could see the message you logged a few days before about a similar issue you identified as a Bug ... then after upgrading MyFaces to Core 1.1.3 + Tomahowak 1.1.2 I could make my test case work.
The further issue I am facing now is that in my Detail view dmexDetails.jsp when I try to POST the form I got for each inputText field the following message :
"inputText field id : Error during model data update "
I "googled" on it without success ... I am still investigating !
