表格没有在第二次ajax电话上提交

Question

所以我正在使用jsf2.2和primeface 3.5。 当我使用h:form（使用ajax调用的此按钮）提交表单时，我有一个@viewScoped带有一些输入字段（p:commandButton支持bean），表单已成功提交。

<p:tabView id="headOfAccountsId_tabview"
                                    onTabChange="mainHeadOfAccountsWidget_blockui.show();shoaWidget_blockui.show();mainHeadOfAccountsWidget_blockui.hide();shoaWidget_blockui.hide();">
                                    <!-- **************************************** Starting Main Head Of Accounts ******************************************* -->
                                    <p:tab title="Main Head Of Accounts" id="mainHeadOfAccountsId_tab">
                                        <p:blockUI block=":#{p:component('mainHeadOfAccountsId_tab')}"
                                            widgetVar="mainHeadOfAccountsWidget_blockui">

                                        </p:blockUI>

                                            </fieldset>

更新表单（update="@form"）后，当我再次提交相同的表单（没有刷新页面）时没有任何反应，任何人都能让我理解实际问题是什么？
