POI 4 XPages中 - 文档生成仅一次 [英] POI 4 XPages - document generation works only once

问题描述

好吧，说实话：标题并不能说明全部真相。我使用的几个按钮（保存，关闭，编辑等）和执行POI操作的按钮自定义的控制 - 这是一个生成的Word文件。
我在这里遇到一个问题：击中POI按钮后，我的其他按钮（和POI之一，也是）将不再起作用，没有点击触发。
现在的怪之一：等待几秒钟后（取决于我使用的浏览器，Chrome是最快的）我能够点击按钮（全部）再次让我可以如离开（关闭）或编辑我的XPage。

Ok, to be honest: the headline doesn't tell the whole truth. I am using a custom control with several buttons (save, close, edit etc.) and a button that executes a POI action - it's generates a Word file. I experience a problem here: after hitting the POI-button my other buttons (and the POI one as well) won't work anymore, no click is triggered. Now the strange one: after waiting a few seconds (depending on which browser I use, Chrome is fastest) I am able to click the buttons (all of them) again so that I can e.g. leave (close) or edit my Xpage.

我不知道是否有帮助，但这里是我的兴趣点按钮的情况下，code：

I don't know if that helps but here is the event code of my POI button:

<xp:button id="button5" styleClass="btn btn-sm printbutton"
            style="display:none">
            <i class="fa fa-print"></i>
            &#160;
            <xp:text>
                <xp:this.value><![CDATA[#{javascript:"Nach MS Word exportieren"}]]></xp:this.value>
            </xp:text>

            <xp:eventHandler event="onclick" submit="true"
                refreshMode="complete">
                <xp:this.action>

                    <xp:actionGroup>
                        <xp_1:generateDocument documentId="wordprint"
                            loaded="true">
                        </xp_1:generateDocument>
                    </xp:actionGroup>
                </xp:this.action>
            </xp:eventHandler>
        </xp:button>

任何想法如何避免这种行为，或者是一个错误的POI 4 XPages中？

Any ideas how to avoid this behavior or is it a bug in POI 4 XPages?

BTW：我不能让Word文档，例如后立即执行其它的动作执行一个脚本或打开一个网页。这将是也打印后，关闭的XPages一种可接受的方式。

BTW: I am not able to execute another action right after getting the Word document, e.g. execute a script or open a page. That would be also an acceptable way to close the xpages after "printing".

在此先感谢！

推荐答案

奥利弗，添加客户端JS调用 XSP.allowSubmit（）来您的按钮，以允许$​​ p $后新提交pssing按钮：

Oliver, add the client-side JS call XSP.allowSubmit() to your button in order to allow new submits after pressing the button:

<xp:button id="button5" styleClass="btn btn-sm printbutton" style="display:none">
        <i class="fa fa-print"></i>
        &#160;
        <xp:text>
            <xp:this.value><![CDATA[#{javascript:"Nach MS Word exportieren"}]]></xp:this.value>
        </xp:text>

        <xp:eventHandler event="onclick" submit="true"
            refreshMode="complete">
            <xp:this.action>
                <xp:actionGroup>
                    <xp_1:generateDocument documentId="wordprint"
                        loaded="true">
                    </xp_1:generateDocument>
                </xp:actionGroup>
            </xp:this.action>
            <xp:this.script><![CDATA[XSP.allowSubmit()]]></xp:this.script>
        </xp:eventHandler>
    </xp:button>
