Hello everyone,
i am trying to call a lazy rule that has a condition as guard. My Problem is that the condition in the lazy rule is not evaluated at all, so i can not filter any objects when calling the lazy rule .

rule FM2FemaleP{
from s: MMFamilies!Member (s.isFemale())

to t: MMPersons!Female (fullName <- s.fisrtName + ' ' + s.refImmediateComposite().lastName,
gf<- thisModule.GF(s)
--calling the lazy rule

lazy rule GF{
from s: MMFamilies!Member (s.hasGF()) --the filter that does not work

to t: MMPersons!Male (fullName <- 'Opi' + '' + s.refImmediateComposite().lastName)

could anyone tell me why is this, i thought that the only difference between normal rules and lazy ones, was how they where called

I have had the same problem.
Instead of putting the condition on the lazy rule, I made a selection before the lazy rule is called.
In this way, the selection is done on beforehand and you don't need a condition in the lazy rule.

I would also like to know why it appears that this condition is not evaluated.
