[rules-users] Need explanation for activation-group attributes.

Hi, Suppose I have the below rules: *Rule "A" salience 100 When then end Rule "B" activation-group "AC1" salience 100 when then end Rule "C" activation-group "AC2" salience 100 when then end Rule "D" activation-group "AC1" activation-group "AC2" salience 90 when then end*// Now the scenarios are: *If B, then no D*, which is happening correctly *If C, then no D*, which is happening correctly *If A, then D*, /This is what is not happening./ Could you please let me know how can I achieve this? If more information required, please let me know. Thanks. Regards, Sudipta Deb. -- View this message in context: http://drools.46999.n3.nabble.com/Need-explanation-for-activation-group-a...
