    Values are not automatically selected on form submit unless the dojo.js is included using the <s:head theme="ajax"/> tag

    If you use doubleOnmouseup in this tag you will get an error. May be it is a freemarker template error. The error is below. Please see the bold text below

    Expression parameters.doubleMnmouseup is undefined on line 217, column 18 in template/simple/optiontransferselect.ftl.
    The problematic instruction:
    ----------
    ==> $

    Unknown macro: {parameters.doubleMnmouseup?html}

    [on line 217, column 16 in template/simple/optiontransferselect.ftl]
    in include "/$

    Unknown macro: {parameters.templateDir}

    /simple/optiontransferselect.ftl" [on line 24, column 1 in template/xhtml/optiontransferselect.ftl]
    ---------- Java backtrace for programmers:
    ----------
    freemarker.core.InvalidReferenceException: Expression parameters.doubleMnmouseup is undefined on line 217, column 18 in template/simple/optiontransferselect.ftl.
