[rules-users] Loading enums programmatically in guvnor

Hi, I am a newbie to drools/guvnor. I am trying to populate a drop-down list in guvnor rule generation with preconfigured values(which would come from database). I tried to populate the titles property of AgeTest class with values from loadData() method of AgeValues class. In the new Enumeration I gave: titles=(new com.guvnor.AgeValues()).loadData(); My classes are as below: public class AgeTest { private List<String> titles = new ArrayList<String>(); public List<String> getTitles() { return titles; } public void setTitles(List<String> titles) { this.titles = titles; } } and public class AgeValues { public Map<String,List<String>> loadData() { Map<String,List<String>> data = new HashMap<String,List<String>>(); List<String> titleValues = new ArrayList<String>(); titleValues.add("title1"); titleValues.add("title2"); data.put("AgeTest.titles", titleValues); return data; } } I get the following error while validating the enumeration: "The expression is not a map, it is a java.util.ArrayList". Can anyone please guide me in this regard. I even tried to have titles field as a map, but same issue. I copied the 2 classes to my guvnor/web-inf folder. -- View this message in context: http://drools-java-rules-engine.46999.n3.nabble.com/Loading-enums-program...
