Re: [rules-users] How to write a rule that fires when it matches against specific facts in working memory.

Edson, I did manage to use the 'CollectSetAccumulateFunction' as a template for the MatchAll and have also successfully 'called' the accumulate function from a rule written in a .drl file. But I'm stuck at one point - how to send the value of $param to the accumulate method ? From what I understand, the accumulate method is invoked for each fact - so if I write MatchAll( $o ) it will invoke the accumulate method and passing $o fact to the method via the 'Object value' parameter. So far so go, however, I'm stuck on how to pass the value of '$param' to the accumulate method (or any other method like init, getResult for that matter). One option I can think of is to change the definition of the Option fact to include a 'param' field and then write a rule that sets the value of that field to $param (so every Options param field would get set to the value of $param). I can then extract that in the accumulate method it self. But is there a better way that I might be missing ?
