[rules-users] Calling queries or collect() from functions

Hi, I have a rule like: rule "Rule1" when $fact: Fact1() $allFacts: ArrayList() from collect(Fact1()) then insert(new Fact2($allFacts.size())); end I want to compute $allFacts inside a function since I will use it across different rules. This doesn't work because it is not valid Java syntax: function int size() { ArrayList a = ArrayList() from collect(InQueuePredicate()); return a.size(); } Could I put this in a named query, and call it from a function? Thanks! Miguel
