[rules-users] Write Assumptions for NESTED List<Object>

Hi i have these simple three POJO class. The first is an OrderType that cointains a List or OrderLineType and each orderline cointains a list of measures. ________________________________________________________ /public class OrderType { protected List<OrderLineType> OrderLine; protected String priority; public void set .... public List<OrderlineType> get .... public getPriority()... public setPriority()... } public class OrderLineType { protected String Quantity; protected List<OrderLineMeasure> OrderLineMeasure; public void set .... public List<OrderLineMeasure> get .... public getQuantity()... public setQuantity()... } public class OrderLineMeasure { protected int measure; protected List<OrderLineMeasure> OrderLineMeasure; public getMeasure()... public setMeasure()... } / ________________________________________________________ I want to write an assumption stating that: *If an ORDER contains at least 3 orderLine... the order must have the High Priority.* In can do that writing this rule: _______________________________________________________________ /when $Order : OrderType ($orderLineList :orderLine) OrderLineType(Quantity.Value >= 3 ) from $orderLineList then $Order.getUBLRuleEnginePriority().setValue("high"); end/ ________________________________________________________________ Now how can i write the assumption? if i want a rule stating: *If an ORDER contains at least 3 orderLine and Each OrderLine contains more than 12 measures... the order must have the High Priority.* Really thanks for your help.
