Re: [rules-users] Getting one type from a collection of multiple types

Thank you for the hints. I have implemented a method to hide the instanceof code, and tried using the accumulate CE. The LHS of my rule is now: $step : Step() $highScore : Number() from accumulate ( $location : VendorAddress () from $step.job.scorableLocations, max($location.abcScore) ) in my RHS I can display the score this way: System.out.println(" MAX SCORE IS: " + $highScore ); and verify that the accumulate is indeed choosing the max score. HOWEVER, what I really want is not the max score, but the ADDRESS with the max score. if I try to use $location in my RHS like this: System.out.println("high score is: " + $location.getAbcScore()); I get compile time exception: [Error: unable to resolve method using strict-mode: org.drools.spi.KnowledgeHelper.$location()] It looks like my $location variable is usable in the LHS but does not get scope to the RHS. -- View this message in context: http://drools.46999.n3.nabble.com/Getting-one-type-from-a-collection-of-m...
