[rules-users] Using functions to derive values in "accumulate" (LHS)

[DroolersEye]

Hi,
rule "Total Cost"
	when
		$trip : Trip( $cost : cost)
		$totalCost : Number() from 
					accumulate( 
							Person( trip== $trip, maxMoney:maxMoney ),                            
							sum( $cost ) 
	   		   			)
	then
		//take action
end

-----
with kind regards,
