Subject Null value in map:select type="parameter"
Date Mon, 03 Aug 2009 06:38:04 GMT

I'm trying to use a map:selector with a parameter. I have 2 cases; when 
the parameter is null or empty and when it has a value. My code looks 
like this:

<map:select type="parameter">
    <map:parameter name="parameter-selector" value="${myParameter}"/>
    <map:when test="">

Is it possible to distinguish whether the value is empty or not?

Thanks in advance.
