freemarker.core.InvalidReferenceException: Error on line 261, column 13 in
--->

It throws the error that like below when I upgrade the struts 2 to version
2.3.15.1 from version 2.2.1.1 FreeMarker template error!
Error on line 261, column 13 in template/simple/optiontransferselect.ftl
stack.findValue(parameters.doubleListKey) is undefined. It cannot be
assigned to doubleItemKey
The problematic instruction:
==> assignment: doubleItemKey=stack.findValue(parameters.doubleListKey)
[on line 261, column 13 in template/simple/optiontransferselect.ftl]
in user-directive s.iterator [on line 259, column 9 in
template/simple/optiontransferselect.ftl]
Java backtrace for programmers:
freemarker.core.InvalidReferenceException: Error on line 261, column 13 in
template/simple/optiontransferselect.ftl
stack.findValue(parameters.doubleListKey) is undefined. It cannot be
assigned to doubleItemKey at
