嗨<h:commandbutton> <f:ajax> <h:datatable>的人不在<h:panelgroup>工作。
它在<h:datatable>和<h:panelGroup id="output4">
<h:dataTable border="1" class="data_table" value="#{admin.list}" var="o">
<h:column>
<f:facet name="header">Id</f:facet>
#{o.id}
</h:column>
<h:column>
<f:facet name="header">İsim</f:facet>
#{o.isim}
</h:column>
<h:column>
<f:facet name="header">Yazar/Yönetmen/Yapımcı/Sanatçı</f:facet>
#{o.yazar}
</h:column>
<h:column>
<f:facet name="header">Yayınevi</f:facet>
#{o.yayinevi}
</h:column>
<h:column>
<f:facet name="header">Fiyat</f:facet>
#{o.fiyat} ₺
</h:column>
<h:column >
<f:facet name="header">İşlem</f:facet>
<h:panelGroup id="userPanel">
<h:panelGroup>
<h:form>
<h:commandButton value="Sil" >
<f:param name="islem" value="2" />
<f:param name="id" value="#{o.id}" />
<f:ajax execute="@this" event="action" id="5"
listener="#{test.deleteRecord()}" />
</h:commandButton>
</h:form>
</h:column>
</h:dataTable>
</h:panelGroup>
之外时有效。但在这种情况下，它不起作用。
