Transfer parameter from jsf with f:attribute to java variable?

Question

I want to transfer parameter #{myvar.tc} with f:attribute component. In the datatable cocukDoktor() method "dr_tc" came. I want to run drgor.sayfaYonlendirme() after parameter transfer. But #{myvar.tc} doesn't transfer. What can I do?

 <h:dataTable value="#{doktor.cocukDoktor()}" var="myvar">
                    <table>
                        <tr>
                            <td>
                                <h:column>
                                <h:graphicImage class="doktorfoto" value="resources/images/doktorfoto.jpg"/>  
                                </h:column>
                            </td>
                            <td>
                                <h:column>
                                     <h:form>
                                         <h:commandLink class="doktorismi" action="#{drgor.sayfaYonlendirme()}" actionListener="#{drgor.drtcAyarla}" >#{myvar.dr_adi} #{myvar.dr_soyadi}
                                             <f:attribute name="dr_tc" value="#{myvar.dr_tc}"/>
                                    </h:commandLink>   
                                    </h:form>
                                </h:column>
                            </td>
                        </tr>
                   </table>
                 </h:dataTable>

        return rs;


    }
    catch (Exception e) {

    finally{

Can you give it a try with

    <h:form>
    <h:dataTable value="#{doktor.cocukDoktor()}" var="myvar">
     <h:column>
        <h:graphicImage class="doktorfoto" value="resources/images/doktorfoto.jpg"/>  
     </h:column>
    <h:column>
      <h:commandLink class="doktorismi" 
                     action="#{drgor.sayfaYonlendirme()}" 
                     actionListener="#{drgor.drtcAyarla}" 
                     value="#{myvar.dr_adi} #{myvar.dr_soyadi}"
     >
     <f:setPropertyActionListener target="#{drgor.tr_tc}" value="#{myvar.dr_tc}" />
     </h:commandLink>   
    <h:column>
    </h:dataTable>
    </h:form>

Anyway, there is no need to do the table HTML stuff, it is done by the dataTable. Also the doctor class is missing to give you more help. To get more satisfying help, you need to provide more information.
