Accessors of java.util.Map implementations use a single parameter. Is
the instance variable behind the "valueNum" property an implementation
of java.util.Map (ie. HashMap,
org.apache.commons.collections.FastHashMap, etc)?
If it is, then Mark's suggestion needs one little tweak.
Change: ${whatever} -> ${whatever.key}
Where "key" is the java.util.Map key, under which, you wish to store
your parameter from your form.
