Hi,       Can you tell me how window:time(..) function is used in drools guided editor?     I have situation where Collection of objects will be there in entry-point. And if one of the objects matches certain criteria and other other objects match certain criteria, then I have to take do something.     In otherwords, Is it possible to specify "when condition" in guided editor using collection of objects for a given time window from entry-point?   Example condition,     when       remTxnData : REMTxnData(transactionType == "P2P")    -- Current object inserted into session       remTxnDataLoad : REMTxnData(remTxnData.accountNumber == accountNumber,   transactionType == "CC_LOAD") over window:time(1m) from entry-point TransactionStream    then       --------   end Thanks Baskaran S   The INTERNET now has a personality.
