[rules-users] forall over a collection

Trying to check whether a patient has a particular problem on their problem list: when $patient : Patient() forall ( Problem( code != "195967001") from $patient.problemList) but I get the following parsing error-- [29,41]: [ERR 101] Line 29:41 mismatched input 'FROM' expecting ')' in rule "Dumb no asthma Rule" [29,66]: [ERR 101] Line 29:66 mismatched input ')' expecting '(' in rule "Dumb no asthma Rule" in pattern $patient.problemList What is the correct way to check for this condition? Thanks, Howard
