Adobe Acrobat 无缘无故地重复表单

Question

这是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（或者更臃肿）而无法发布。因此，如果您打开 Adob​​e LiveCycle 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。如果您打开 pdf 并保存它，您将看到子表单从显示一次变为显示两次。有谁明白为什么此代码/标记会导致在保存表单时创建另一个实例？

我对 LiveCycle 不太熟悉，无法理解所有生成的语法，但似乎没有任何东西应该这样做。我认为负责添加另一个表单实例的按钮可能在我不知情的情况下被触发，但情况似乎并非如此，因为完全删除按钮并不能解决问题。

Answer 1

所以这个问题通过删除一个空的子表单来“解决”。没有人知道为什么，但是删除子表单并为所有元素赋予唯一的名称可以防止元素重复。

已将此错误报告给 Adob​​e。
