the parameter in $currentObject is always Null in XPath of List view

I have one main page with  data view PaymentTran which is through microflow to get, and one button to show the bank search page. in the main page the $currentObject/CountryCode can work in XPath in List view, but when show the bank search page which contains List view. the $currentObject/CountryCode is always is NULL in the XPath, $currentObject is the context of the page of PaymentTran (in main page) but I can see the value  of $PaymentTran/CountryCode in the bank search page for input text.  is the Mendix limit  or something wrong of my design?
