All, I was wondering [and maybe this has be answered before] ,but does the order of the rules in the when clause matter? For example I have the following: rtvHeader : RtvHeader( headerRtvNumber : rtvNumber ) repaymentCode : RepaymentCode( actualCode : code, matchApprv != "Y" ) lineCharge : HeaderAdditionalCharge( rtvNumber == headerRtvNumber, originalRepaymentCode == actualCode ) In my case there is a higher likelihood that I will have more RepaymentCodes than RtvHeaders [1 of these guys] and likely less HeaderAdditionalCharge objects. So should the order be more like: rtvHeader : RtvHeader( headerRtvNumber : rtvNumber ) lineCharge : HeaderAdditionalCharge( rtvNumber == headerRtvNumber, originalRepaymentCode : originalRepaymentCode) repaymentCode : RepaymentCode( actualCode == originalRepaymentCode, matchApprv != "Y" ) Or does it not really matter?
