[rules-users] Reg: Writing complex rules in Grided editor

Hi,          I am new to Drools rules. Can any one of you tell me how can we write complex rules like below using Grided editor.   rule sequenceOfIncreasingWithdrawals   when     $account:Account($number : number)     $t1:TransactionCreatedEvent(fromAccountNumber == $number)       from entry-point TransactionStream        $t2:TransactionCreatedEvent(amount > $t1.amount,       fromAccountNumber == $number, this after[0, 3m] $t1)       from entry-point TransactionStream     not (TransactionCreatedEvent(fromAccountNumber == $number,       this after $t1, this before $t2 )       from entry-point TransactionStream)     $t3:TransactionCreatedEvent(amount > $t2.amount,       fromAccountNumber == $number, this after[0, 3m] $t2 )       from entry-point TransactionStream     not (TransactionCreatedEvent(fromAccountNumber == $number,       this after $t2, this before $t3 )       from entry-point TransactionStream)     $ai : AccountInfo(number == $number, eval($t1.amount.add(       $t2.amount).add($t3.amount).compareTo(BigDecimal.       valueOf(0.90).multiply(averageBalance)) > 0))   then     insert(new SuspiciousAccount($number,       SuspiciousAccountSeverity.MAJOR));     insert(new SuspiciousTransaction($t1.transactionUuid,       SuspiciousTransactionSeverity.MAJOR));     insert(new SuspiciousTransaction($t2.transactionUuid,       SuspiciousTransactionSeverity.MAJOR));     insert(new SuspiciousTransaction($t3.transactionUuid,       SuspiciousTransactionSeverity.MAJOR)); end     Thanks Baskaran S Yahoo!
