It may be easier to write rules if you assert more of your object model into WM as opposed to the deep nesting. dbtrAcct.?id == null, dbtrAcct.?id.?othr == nulll, etc. Rule 1 checks all the nested attributes are not null and set the status as invalid if any of them is null. I assume the LHS of rule 2 will be short circuited if the object is invalid. find more info

Rule 2 uses the and operator and checks the nested attribute is in the collection defined by the global, only if the object is valid. dave2010/7/16 Meeraj Kunnumpurath <[hidden email]> Hi,I have the following rules,global java.util.Set accountNumbers;rule "rule 1"when    $d : Document()    $c : CreditTransferTransactionInformation (dbtrAcct == null || dbtrAcct.id == null || dbtrAcct.id.othr == null dbtrAcct.?id == null, dbtrAcct.?id.?othr == nulll, etc. Kind regardsMeeraj 2010/7/16 David Sinclair <[hidden email]> Drools doesn't use short circuit evaluation, so all of those ORs are going to be evaluated.
