[rules-users] column contraint + java bean

hi all, having trouble with Drools 3.x syntax. currently using one fact in working memory that is a aggregate of many java beans. However when using the column constraint syntax it does not seem to allow nested getXXX on the column constraint. I have it working using predicate but it just seems verbose. i would like to be able to fire rule when the table object has a player count > 0 and the Table.getDealer.getFlop() == null how is this done on Drools 3.x? ie. public class Table{ int playerCount; Dealer dealer; Collection players; .... } rule "start" no-loop true when table : Table( playerCount > 0 , dealerFlop : dealer->(dealerFlop.getFlop() == null ) ) then System.out.println( "start:" + table.getDealer().getFlop() ); end many thanks -lp
