Pdf AdobeAcrobat正在毫无理由地重复一个表单

这里有一个简单的表格来帮助说明这个问题。这不是表单的完整代码，因为它太长（或者说太臃肿），无法发布。因此，如果打开AdobeLiveCycle并创建一个空白文档，请插入以下内容作为主要内容

然后将其另存为pdf。如果打开pdf并保存，您将看到子窗体从显示一次变为显示两次。有人知道为什么保存表单时，此代码/标记会导致创建表单的另一个实例吗

我对LiveCycle还不够熟悉，无法理解所有生成的语法，但似乎没有什么东西可以做到这一点。我认为可能是负责添加另一个表单实例的按钮在我不知道的情况下启动了，但情况似乎并非如此，因为完全删除按钮并不能解决问题

子窗体
去除
var inst=Form.instanceManager；
如果（安装计数1）{
inst.removeInstance（inst.count-1）；}else{
xfa.host.messageBox（“允许的最小字段数为1。您不能删除更多字段。”，“警告”，3）；}
添加更多
Form.instanceManager.addInstance（1）；

因此，通过删除一个空的子表单，“修复”了此问题。没有人知道为什么，但是删除子表单并为所有元素指定唯一的名称可以防止元素重复

据Adobe报告，这是一个bug
