I’m receiving errors when compiling my .drl files as a result of using Java generics. Example: rule "Rule 1 - Testing" no-loop true when $orderInfo : OrderingInfo (orderedProducts != null) then Customer customer = $orderInfo.getCustomer(); ArrayList<ProductAttribute> productAttributes = $orderInfo.getAttributes(); String localCode = getCode(customer); end It complains that ArrayList<ProductAttribute> cannot be resolved … actual error is below: RuleBaseTask failed: Unable to resolve type ArrayList<ProductAttribute>: Unable to find class 'ArrayList<ProductAttribute>' : [Rule name='Rule 1 - Testing'] Is there a resolution to this problem? Thank you in advance. -- View this message in context: http://drools.46999.n3.nabble.com/Drools-5-4-and-Java-Generics-tp4019327.... Sent from the Drools: User forum mailing list archive at Nabble.com.
