PrimeFaces嵌套表单在p:对话框中,其中appendTo ="@(body)

Question

我有这个片段:

<h:form id="form">

    <!-- other content -->

    <p:panel id="panel" header="test">
        <p:inputText id="input1" value="#{viewScope.prop1}" required="true" />
        <p:commandButton id="button1" process="@form" update="@form @widgetVar(dialog)"
            oncomplete="PF('dialog').show()" value="ok" />
    </p:panel>

    <!-- other content -->

</h:form>

<p:dialog id="dialog" header="dialog" widgetVar="dialog" modal="true">
    <h:form id="form2">
        <p:inputText id="input2" value="#{viewScope.prop1}" required="true" />
        <p:commandButton id="button2" process="@form" update="@form" value="ok" />
    </h:form>
</p:dialog>

一切都按预期工作.

我想要达到的目的是:

<h:form id="form">

    <!-- other content -->

    <!-- fragment start -->
    <!-- this fragment will be on its own file and included via ui:include (or inside composite component) -->
    <p:panel id="panel" header="test">
        <p:inputText id="input1" value="#{viewScope.prop1}" required="true" />
        <p:commandButton id="button1" process="@form" update="@form @widgetVar(dialog)"
            oncomplete="PF('dialog').show()" value="ok" />
    </p:panel>

    <p:dialog id="dialog" header="dialog" widgetVar="dialog" modal="true" appendTo="@(body)">
        <h:form id="form2">
            <p:inputText id="input2" value="#{viewScope.prop1}" required="true" />
            <p:commandButton id="button2" process="@form" update="@form" value="ok" />
        </h:form>
    </p:dialog>
    <!-- fragment end -->

    <!-- other content -->

</h:form>

但我没有成功尝试的某种组合process,并update为button1导致处理任何事情...... input1甚至重新...

那么,如何构建一个p:dialog可以在片段或复合comp中发布并且从外部排除的form？

请注意使用:

<h:form id="form">

    <!-- other content -->

    <ui:include src="panel.xhtml" />

    <!-- other content -->

</h:form>

<ui:include src="dialog.xhtml" />

是不可接受的解决方案.

我使用的是JSF 2.2.8(mojarra)和PF 5.1

最后，我找到了一种使用OmniFaces 的方法，其中<o:moveComponent />：

页：

<h:form id="form">

    <!-- other content -->

    <ui:include src="/fragment/with/inner/form.xhtml" />

    <!-- other content -->

</h:form>

分段：

<ui:composition>    
    <p:inputText id="outerText" value="#{viewScope.text}" />

    <p:commandButton id="openButton" process="@form" update="@widgetVar(testDialog)"
        oncomplete="PF('testDialog').show()" value="open" />
    <o:moveComponent id="move" for=":#{facesContext.viewRoot.clientId}" destination="ADD_LAST">
        <h:form id="innerForm">
            <p:dialog id="dialog" widgetVar="testDialog" header="test dialog">
                <p:inputText id="innerText" value="#{viewScope.text}" />

                <f:facet name="footer">
                    <p:commandButton id="confirmButton" process="@form" update=":form"
                        oncomplete="if(!args.validationFailed) PF('testDialog').hide()" 
                        value="submit" />
                </f:facet>
            </p:dialog>
        </h:form>
    </o:moveComponent>
</ui:composition>

这会引起一些警告：

WARNING Unable to save dynamic action with clientId 'form:innerForm:dialog' because the UIComponent cannot be found
WARNING Unable to save dynamic action with clientId 'form:innerForm:innerText' because the UIComponent cannot be found
WARNING Unable to save dynamic action with clientId 'form:innerForm:confirmButton' because the UIComponent cannot be found

因为恢复的组件不会在后续回发时重新删除RESTORE_VIEW。

对于我的实验来说，这些警告是无害的，可以安全地忽略。

不过，我打开了一个拉取请求以最终修复它。
