我试图用重复的网格在orbeon窗体（4.10 PE）中创建窗体。我想用请求参数填写这个表单。但是，似乎当我使用xf：insert替换主数据实例时，xml以某种方式转换。Orbeon窗体生成重复标签
我在http://localhost:8080/orbeon/fr/test/test公开为测试/检验以下最低形式：

我然后采取“FR-形式实例”实例的内容和Base64编码的XML。然后，我发布使用一个简单的HTML表单的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>
当我看到在Orbeon的“FR-形式实例”实例窗体的XForms督察我看到有一个多余的“mygrid迭代”迭代标记和控件不呈现。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。
我做错了什么？这是Orbeon中的错误吗？如果是这样，是否有一个已知的解决方法？
