[rules-users] can we mix java n mvel dialect in LHS

Hello, I have some drools beginner questions 1.what is default dialect if it is not specified? 2. can We mix java and mvel syntax in LHS? Ex: class Cheese(String type,Set<String> ingredients) Is this valid LHS? when cheese : Cheese(ingredients.getIngredients().size > 3,type == "American") 3. In my sample program , I have a following condition which never executes even if i have "sugar" ingredient. any help? when cheese : Cheese(ingredients contains "sugar") -- View this message in context: http://www.nabble.com/can-we-mix-java-n-mvel-dialect-in-LHS-tp20330087p20...
