Re: [rules-users] Concatenating rule conditions

Not sure of what you exactly ... If you want to combine tests, you can write this : Rule "test filter" When $cm: ConditionMatrix() $document: ArrayList() from collect ( Document (user.isPrivateName == $cm.isPrivateName, Payment.isLegal == $cm.isLegal) ) Then //do something End If you want to make the filter more dynamic and write only one "collect" rule, I don't see any out-of-the-box method. You can add a method in ConditionMatrix that accepts a Document and write this rule : Rule "test filter" When $cm: ConditionMatrix() $document: ArrayList() from collect ( Document (eval($cm.accept(this))) ) Then //do something End Of course you have to implement the "accept" method in Java (and you can then do several sub-classes for you filters)
