Hi Ronan,
I think your problem come from the call. A lazy rule is called on a
collection, not on an element. You can try to call your lazy rule on a
collection of MMa!Mappings without any change, or transform your lazy
rule on a called rule :
<- thisModule.MappingsToAssign(mp);
rule MappingsToAssign (mp : MMa!Mappings) {
to
ass : MMb!Assign()
}
But you have to check the condition (mp."from".message = 'Initial')
before calling.
Best regard,
Régis Chevrel (Sodius)
