我正在使用表单生成器（版本4.9）来创建包含重复网格的表单。 我还定义了一个Process按钮，以便将表单的数据发送到Servlet（使用send（）方法）。 我的目标是将表单数据保存在数据库表中。
我能够在servlet中以XML的形式接收Form的数据，但我注意到在不同的迭代中具有相同值的字段， 在XML中每个值只出现一次，具有带有多个值的“for”属性（表示值重复的数量）。 但是，我无法找到匹配同一迭代的所有字段的方法（表示一个表行），因此我无法正确地将数据存储在数据库中。
例如，当我发布下表
时HEADERS : FIELD_B - FIELD_C -
ITER_1 : FIELD_B_1 - FIELD_C_1 -
ITER_2 : FIELD_B_2 - FIELD_C_2 -
ITER_2 : FIELD_B_3 - FIELD_C_1 -
我得到以下XML
<?xml version="1.0" encoding="UTF-8"?>

如您所见，在迭代1和3中，FIELD_C包含值FIELD_C_1。 解析XML时，我无法找到该字段值的顺序。我最终得到了错误的表：
HEADERS : FIELD_B - FIELD_C -
ITER_1 : FIELD_B_1 - FIELD_C_1 -
ITER_2 : FIELD_B_2 - FIELD_C_1 -
ITER_2 : FIELD_B_3 - FIELD_C_2 -
迭代2和3在FIELD_C中有错误的值。
如何找到重复字段值的正确顺序？
我正在寻找一种不需要在表单构建器外部操作表单定义的解决方案，因为表单将由最终用户创建，而不了解XForms。
properties-local.xml中的提交按钮是：
<property
as="xs:string"
name="oxf.fr.detail.process.OrbeonFormsPortlet.*.*">
validate-all
then send(
property = "oxf.fr.detail.send.success",
uri = "http://localhost:8080/web/guest/testlang/-/oaed-form-requests/pop_up/{xxf:get-request-header('Orbeon-Liferay-User-Id')}",
content = "metadata",
prune = "false"
)
</property>
完整的表单定义是（表单包含一个字段 - FIELD_A - 外部重复网格，与问题无关）：

我确实重现了这一点，这似乎是一种疏忽。对控制数据进行分组以优化输出大小，但我现在发现这可能会导致问题！
我不确定在给定当前结构的情况下可以正确推断订单。我在此添加了issue。
