[rules-users] can not use mvel to access object in a map in THEN

rule "Simple Rule" dialect "mvel" when $record: Record(dataMap["abc"]=="123") then System.out.println($record.dataMap["abc"]); end I got Exception when loading this rule. dataMap is a map in class Record. It seems $record.dataMap["abc"] doesn't work in "THEN". Does anyone know why? Unable to build expression for 'consequence': 1 ' System.out.println($record.dataMap["abc"]); ' : [Rule name='Simple Rule'] java.lang.IllegalArgumentException: Could not parse knowledge. -- View this message in context: http://drools.46999.n3.nabble.com/can-not-use-mvel-to-access-object-in-a-...
