Orbeon JavaScript Embedding error: `ORBEON.xforms.server.AjaxServer.Event is not a constructor`

Orbeon JavaScript Embedding error: `ORBEON.xforms.server.AjaxServer.Event is not a constructor`

我正在尝试使用 JavaScript Orbeon 嵌入 API。设置转发后*(我希望是正确的,我先有 404,然后是 CORS 错误)现在表单已嵌入到页面中但表单不起作用,单击任何 control/button 都会导致错误 ORBEON.xforms.server.AjaxServer.Event is not a constructor.

更具体地说,单击下一页按钮会在控制台中产生:

xforms.js:2399
⌄ Uncaught TypeError: ORBEON.xforms.server.AjaxServer.Event is not a constructor
    at HTMLDocument.focus (xforms.js:2399)
focus @ xforms.js:2399
---
xforms.js:2722 
⌄ Uncaught TypeError: ORBEON.xforms.server.AjaxServer.Event is not a constructor
    at HTMLDocument.click (xforms.js:2722)
click @ xforms.js:2722

* 转发是这样设置的:

<VirtualHost *:443>
    ....
    SSLProxyEngine on
    RewriteEngine  on
    RewriteRule    "^/orbeon/(.+)"  "https://orbeon.server.ip/orbeon/"  [P,L]

JS Embedding API Limitations状态,即

oxf.xforms.combine-resources must be set to true

(在properties-local.xml)
