[rules-users] get list from map object

Hi, One of the class member of the fact is map<String,List>. In the DRL file I need to get list from the map(I know the map key) and set it to variable name $theList. Then I need to check if some variable is memberof $theList Can you please advice how to get the list from the map and set the $theList variable? For example : public class Cheese { private String type; private Map<String,List<Integer>> map; public Cheese(String type) { this.type = type; } public String getType() { return type; } public void setType(String type) { this.type = type; } public Map<String, List<Integer>> getMap() { return map; } public void setMap(Map<String, List<Integer>> map) { this.map = map; } public List<Integer> getListFromMap(String name) { return map.get(name); } } DRL file - rule "Cheese_fans_18" when Cheese($theList :* don't know how to get the list from the map*) Cheese(type memberof $theList) then System.out.println("Cool"); end Thanks, Meny
