所以我已按照以下内容更改了代码

So I have changed my code as per below

                    <p:commandLink id="addRequest" immediate="true" value="addreq"
                    oncomplete="dlg3.show()" update="dialogPanel">
                    <f:setPropertyActionListener
                        value="#{searchHandler.selectedAccIns}"
                        target="#{reqSearchHandler.checkAccStatus}" />
                </p:commandLink>

对话框是

                <p:outputPanel id="dialogPanel"
                rendered="#{not reqSearchHandler.accStatusFlag}">
                <p:dialog header="Effect Dialog" widgetVar="dlg3"
                    showEffect="bounce" hideEffect="explode" height="200">
                    <h:outputText
                        value="Account is #{searchHandler.selectedAccIns.accStatusDesc}" />
                    <h:outputText value="Do you want to continue?" />
                    <div align="left">
                        <p:commandButton value="Yes" action="accept" />
                        <p:spacer width="960" height="5" />
                        <p:commandButton value="No" action="cancel" />
                    </div>
                </p:dialog>
            </p:outputPanel>

但是，当我单击命令链接时，会出现3个对话框.你能告诉我为什么吗?

But when I am clicking on the command link , I am getting 3 dialog boxes. Can you please tell me why it is so?

推荐答案

其他人刚刚发布了相同的问题！ :)

Somebody else just posted the same problem! :)

您应该使用oncomplete属性而不是commandButton的onclick.在页面回发之前，将发生click javascript事件，这可能是由于页面重新加载而导致对话框无法显示.

You should use the oncomplete attribute instead of onclick of the commandButton. The click javascript event occurs before the page posts back, likely causing your dialog not to appear because of the page reloading.

oncomplete="dlg3.show()"将在回发后显示对话框.

oncomplete="dlg3.show()" will display the dialog AFTER the postback.
