Hi Mark,
Can you tell me what is wrong then with a rule below (WHEN part provided):
when
$order: Order( $orderId: id, $userId: userId, $orderParts:
orderPart /*
this is a collection */ )
$user: User( id == $userId, $userOrderMoneyLimit:
orderMoneyLimit )
Double( $orderTotal: doubleValue ) from accumulate (
OrderPart( $orderPartItemId: itemId,
$orderPartItemAmount: amount ) from
$orderParts
Item( $itemPrice: price, id == $orderPartItemId ), //
Line NNN
init( double total=0; ),
action( total += $itemPrice * $orderPartItemAmount; ),
reverse( rval -= $itemPrice * $orderPartItemAmount; ),
result( total )
)
I got an error:
mismatched input 'Item' expecting ')' in rule "XXX"[NNN,53]: [ERR 102] Line
NNN:53 mismatched input ',' expecting 'then' in rule "XXX"
I tried to group both patterns with () but with the same result.
Also, by changing rule to the one below (by removing second pattern and
simulating $itemPrice):
when
$order: Order( $orderId: id, $userId: userId, $orderParts:
orderPart /*
this is a collection */ )
$user: User( id == $userId, $userOrderMoneyLimit:
orderMoneyLimit )
Double( $orderTotal: doubleValue ) from accumulate (
OrderPart( $orderPartItemId: itemId,
$orderPartItemAmount: amount ) from
$orderParts,
init( double total=0; double $itemPrice=3.33; ),
action( total += $itemPrice * $orderPartItemAmount; ),
reverse( rval -= $itemPrice * $orderPartItemAmount; ),
result( total )
)
Everything works fine.
So, it looks like that problem is related to Second pattern. Is there some
special syntax for it?
