Question

经过这么多搜索后，在点击主要对话框中点击命令按钮后，我无法找到更新数据表的方法。

我的mainMenu.xhtml有一个数据表，如：

<section id="ownermanagement">

<h:form id="ownermanagementform">
    <p:commandButton class="btn icon-cart" actionListener="#{ownerControl.viewNewOwnerDialog()}" value="کارفرما جدید"/>
    <br></br><br></br>
    <p:growl id="growl" showDetail="true"/>
    <p:dataTable filterEvent="enter" id="ownerdatatable" value="#{ownerControl.ownerList}" var="owners" dir="rtl" emptyMessage="موردی با این مشخصات یافت نشد." style="border: 1px solid black;">
        <p:column filterBy="#{owners.id}" filterMatchMode="contains">
            <f:facet name="header">شناسه</f:facet>
                #{owners.id}
        </p:column>
        <p:column filterBy="#{owners.name}" filterMatchMode="contains">
            <f:facet name="header">نام</f:facet>
                #{owners.name}
        </p:column>

        <p:column>
            <f:facet name="header">عملیات</f:facet>
            <p:commandButton value="ویرایش کارفرما"
                             actionListener="#{ownerControl.viewEditOwnerDialog(owners)}" update="ownerdatatable"/> |
            <p:commandButton value="حذف کارفرما"
                             action="#{ownerControl.removeOwner(owners)}"
                             onclick="return confirm('آیا از حذف کارفرما اطمینان دارید؟')"
                             update="ownerdatatable"/> 
        </p:column>

    </p:dataTable>

</h:form>
</section>

我打开我的对话框：

<p:commandButton class="btn icon-cart" actionListener="#{ownerControl.viewNewOwnerDialog()}" value="کارفرما جدید"/>

viewNewOwnerDialog方法是：

public void viewNewOwnerDialog() {
    Map<String, Object> options = new HashMap<String, Object>();
    //options.put("modal", true);
    options.put("resizable", false);
    resetInputs();
    RequestContext.getCurrentInstance().openDialog("createOwner", options, null);
}

这将在对话框中打开我的createOwner页面：

<?xml version='1.0' encoding='UTF-8' ?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

      xmlns:p="http://primefaces.org/ui">
    <h:head>
        <title>کارفرما جدید</title>
        <link rel="stylesheet" type="text/css" href="resources/style/elements.css" />
    </h:head>
    <h:body dir="rtl">
        <h:form id="newOwnerForm">
            <p:growl id="growl" showDetail="true" sticky="true"/>
            نام: <h:inputText class="InputField" value="#{ownerControl.owner.name}"/>
            <br></br><br></br>
            توضیحات: <p:inputTextarea class="textArea" value="#{ownerControl.owner.description}" rows="5" cols="100" counter="display" maxlength="500" counterTemplate="{0}" autoResize="false" />
            <h:outputText id="display" /><br></br>
            <p:commandButton class="btn icon-cart" value="ثبت" action="#{ownerControl.insertOwner()}"  process="@all"  update=":ownermanagementform:ownerdatatable"/>
        </h:form>
    </h:body>
</html>

如何更新咆哮以显示消息，然后更新mainMenu的数据表？

目前，我收到此错误：

Cannot find component with expression ":ownermanagementform:ownerdatatable" referenced from "newOwnerForm:j_idt10".

谢谢！

我解决了这个问题：

<p:commandButton value="Open Dialog" actionListener"...">
   <p:ajax event="dialogReturn" update="datatableID"/>
</p:commandButton>
