我查看了浏览器，它被编译为：
<select id="j_idt30:voucherBeanVoucherVeiculo" name="j_idt30:voucherBeanVoucherVeiculo" class="form-control" size="1"> <option value="" selected="selected"></option>
<option value="61">1560</option>
<option value="97">1870</option>
...............
</select>
我尝试更新此按钮以选择一个菜单：
<p:commandButton action="#{veiculoBean.updateModal()}" value="#{msg['btn-save']}" styleClass="btn btn-primary" >
<p:ajax update=":j_idt30:voucherBeanVoucherVeiculo"/>
</p:commandButton>
答案 0 :(得分：2)
您的表单上有prependId=false。这被ajax调用忽略（根据规范）。所以删除它，给表单一个id并在更新中使用它。另请参阅UIForm with prependId="false" breaks <f:ajax render>
