我正在尝试使用重复网格以orbeon形式（4.10 PE）创建表单。我想使用请求参数填写此表单。但是，似乎当我使用xf：insert替换主数据实例时，xml以某种方式被转换。
我在http://localhost:8080/orbeon/fr/test/test发布了以下最小表格作为测试/测试：

然后我获取'fr-form-instance'实例的内容，base64编码xml。然后我使用一个简单的html表单发布xml：
<html>
<head>
</head>
<body>
<form method="post" action="http://localhost:8080/orbeon/fr/test/test/new">
<input type="hidden" name="fr-form-data" value="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"/>
<input type="submit" value="submit" />
</form>
</body>
</html>
当我查看Orbeon Forms XForms Inspector中的'fr-form-instance'实例时，我发现有一个额外的'mygrid-iteration'迭代标记，并且没有呈现控件。下面是Forms Inspector中显示的xml：
<form>
<section-1>
<control-1/>
<mygrid>
<mygrid-iteration>
<mygrid-iteration>
<control-5>vijf</control-5>
<control-6>zes</control-6>
</mygrid-iteration>
<mygrid-iteration>
<control-5/>
<control-6/>
</mygrid-iteration>
</mygrid-iteration>
</mygrid>
</section-1>
</form>
注意额外的mygrid迭代。
我做错了吗？这是Orbeon的一个错误吗？如果是这样，是否有一个已知的解决方法？
答案 0 :(得分：0)
4.8之前，Orbeon Forms没有＃34;迭代＆＃34; XML中的元素。你刚才有<mygrid>，那个元素本身就重复了。然后4.8引入了一个迭代元素，但为了向后兼容，在将数据保存到数据库或sending data时删除了迭代元素，并在从数据库加载数据时添加了receiving the data through a POST。
在最后一种情况下，如果您想拥有该迭代元素，请将data-format-version=edge添加到您的请求中，Orbeon Forms不会尝试添加迭代元素。
