[rules-users] Map using from constraint

Hi all, Is there a way using the 'from' constraint to get the values of a map(the implementations of java.lang.Map eg HashMap, TreeMap, etc) into a constraint parameter, and if so can someone please give an example. Below is the way I've been trying, without success, to get a value based on a key. import my.package.MyFact import java.util.Map.Entry rule "Find with map" when $fact : MyFact($paramMap : paramMap) $myValue : Entry(key == "mykey1") from $paramMap Then // Sudo code... <use $myValue.getValue()> end Paul Ryan Software Architect Product Engineering InfoTrust Group, Inc.
