## What I really want to do is:       #set ( $listKey = ${param.${parameters.listKey}} )
## However, velocity doesn't allow nested ${'s.  So we have to go to all this effort!
## see http://www.mail-archive.com/[e-mail]/msg09369.html for more information

#set ($param_prefix = '$param.')  ## This is because we use $param in the foreach block below
#set ($prefix_key = "$param_prefix$parameters.listKey")
#set ($prefix_value = "$param_prefix$parameters.listValue")

#foreach ($param in $parameters.list)
    #set ($listKey = $webwork.evaluate("$prefix_key"))
    #set ($listValue = $webwork.evaluate("$prefix_value"))

    <option value="$listKey"
        #if ($contain.contains($parameters.nameValue, $listKey) == true)
            selected="selected"
