Xpath 设置值和绑定问题：值设置为空值

我正在设计一个XForm搜索表单。这是我的密码

这张表格大部分是按照它写的那样做的。我们将输入输入到两个输入中，然后通过绑定设置数据存储中的两个存储节点

然后单击搜索按钮，但是似乎从未调用setvalue，并且没有设置请求/准则/准则中的值节点

知道我做错了什么吗？

所以问题如下：

原始设置值：

<xforms:setvalue ref="/value[1]" value="../../../dataStore/store[@name='CritCallCustomerLastName1']" /> 
<xforms:setvalue ref="/value[2]" value="../../../dataStore/store[@name='CritCallCustomerLastName2']" /> 

解决办法是：

<xforms:setvalue ref="value[1]" value="../../../../dataStore/store[@name='CritCallCustomerLastName1']" /> 
<xforms:setvalue ref="value[2]" value="../../../../dataStore/store[@name='CritCallCustomerLastName2']" />

该实例是criteria节点，因此ref应该是“value[*]”，而该值指向value节点，因此我们必须提升一个额外的级别
