hi. i'm using drools for the first time and i'm running into a problem using a global in the lhs. here's the situation
i have a service object set as a global
i want to call a method on this object that returns a boolean
i can use it in the rhs no problem but in the lhs i get compilation errors
so for example, i can do this no problem:
rule checkExistingSub
when
$s : SubscriberModel()
$c : CollectiveModel()
then
collectiveService.isMember($s, $c);
end
however when i try this:
rule checkExistingSub
when
$s : SubscriberModel()
$c : CollectiveModel()
collectiveService.isMember($s, $c);
then
end
i get this:
[23,29]: unknown:23:29 Unexpected token '$s'
i've experimented a bit but just can't get it to work. so my questions are:
is this possible?
if so, what am i missing?
for any body interested, wrapping the service call in eval() works like so:
rule checkExistingSub
when
$s : SubscriberModel()
$c : CollectiveModel()
eval (collectiveService.isMember($s, $c));
then
end
pretty sure i had tried this before posting but guess not
