我想將參數＃{myvar.tc}與f：屬性組件一起傳輸。在datatable cocukDoktor（）方法「dr_tc」來了。我想在參數傳輸後運行drgor.sayfaYonlendirme（）。但＃{myvar.tc}不會傳輸。我能做什麼？從jsf將f：屬性傳遞給java變量？
<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>
