I tried to use the <s:doubleselect> tag but I get a FreeMarker template
error.
*FreeMarker template error!*
Error on line 122, column 65 in template/simple/doubleselect.ftl
Expecting a string, date or number here, Expression
parameters.doubleNameValue is instead a
freemarker.ext.beans.ArrayModel
The problematic instruction:
----------
==> ${parameters.doubleNameValue} [on line 122, column 63 in
template/simple/doubleselect.ftl]
in include "/${parameters.templateDir}/simple/doubleselect.ftl" [on
line 25, column 1 in template/css_xhtml/doubleselect.ftl]
----------
Java backtrace for programmers:
----------
