[jboss-user] [Beginners Corner] - drools, globals and lhs method calls

[eng@upocnetworks.com]

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?
