Re: [rules-users] Alternative to instanceof when matching against multiple concrete types under the same hiearchy?

Inverting the order of patterns (and following Lisa's idea) makes the problem go away: rule "asdf" when OtherType( $member : member ) Interface( this == $member ) then // do whatever with $member end This can be constrained to a subset of subclasses if there is also ConcreteType3 extends Interface which should not be matched by adding expressions using instanceof. -W -- View this message in context: http://drools.46999.n3.nabble.com/Alternative-to-instanceof-when-matching...
