ADF Faces table and link to detail

Question

Hi all,
I am trying to create a link to a detail page from an ADF table. My problem is, that the action is invoked as often as there are entries in my table. Interesting enough the param "objektId" each time contains the same primary key from the link that has been chosen. This is the code that I am using:
<h:form>
<af:table value="#{organisationListe.trefferzeilen}" var="row">
<af:column sortable="false" formatType="text">
<h:commandLink action="#{organisationListe.showDetail}">
<f:param name="objektId" value="#{row.trefferobjektId}"/>
<af:outputText value="#{row.anzeige01}"/>
</h:commandLink>
</af:column>
</af:table>
</h:form>
Does anyone know the reason for this behavior?
FYI: I don't want to use TableSelectOne as I do not want to have a radio button next to the rows - the customer insists on having a link.
Regards
Peter

Hi,
1. you don't need <af:outputText value="#{row.anzeige01}"/> if using af:commandLink because it has a text attribute. Less code is less work.
2. You cannot use the parameter for this because the request map always shows empty, try
          <af:column sortable="false" headerText="Details">
            <af:commandLink text="Detail for #{row.EmployeeId}"
                            action="#{ShowDetailLinkInTableBean.showDetail}"
                            partialSubmit="true">
              <af:setActionListener from="#{row.EmployeeId}"
                                    to="#{sessionScope.empId}"/>
            </af:commandLink>
          </af:column>in the mangaged bean
    public String showDetail() {
        FacesContext fctx = FacesContext.getCurrentInstance();
        System.out.println("---"+fctx.getExternalContext().getSessionMap().get("empId"));
        return null;
    }Note that even when using f:param the code never executes more than one time
