XFORMS:触发了多个xforms提交完成事件

Question

我遇到过这样一种情况:在执行另一个xforms:send之前，正在检查来自web服务的响应(身份验证)。我遇到的问题是，表单提交和身份验证都命中了xforms-submit- for。

代码如下：

 <xf:action ev:event="xforms-submit-done" ev:observer="Authenticate-submission" context="instance('fr-service-response-instance')">
    <xf:action if="contains(//AuthenticateReturn,'true')"> 
         <!-- If correctly Authenticated, then continue with the form submission -->
         <xf:send submission="SubmitForm-submission"/>
         <xf:action ev:event="xforms-submit" ev:observer="SubmitForm-submission" />
         <!-- Response actions -->
         <xf:action ev:event="xforms-submit-done" ev:observer="SubmitForm-submission" context="instance('fr-service-response-instance')">
             <!-- This section is entered twice, once for the Authenticate-submission andonce for the SubmitForm-submission -->
             <xf:message level="modal">Submission complete</xf:message>    
         </xf:action>
    </xf:action>
 </xf:action>

我如何修改我的代码，以确保消息只在成功提交到SubmitForm-SubmitForm而不是Authenticate-SubmitForm之后显示？

已修复，方法是在xforms-submit-done处理程序中将ev.observer更改为ev.target。
