I have to check which objects in list matches with hashMap. i can iterate list and check it with hashMap but i am not able to get value from from the hashmap which itself is an custom object and i need to check its value below code i am using to iterate list and check it from hashMap when TempStorage($object : concentrationDataTable ) TempStorage($mapObject : concPercentRefObjects) $dataObject : ConcentrationDataTable($keyObject : concPercentRefkey) from $object eval( $mapObject.get($keyObject) != null) I want to add variable to get this value *$mapObject.get($keyObject)* and also check if its property getMax returns me other than 10 -- View this message in context: http://drools.46999.n3.nabble.com/getting-object-from-hashMap-in-when-cla...
