Hello all, The Fame code generator does not generate "container" annotation. ex : if in a MSE file (FM3.Property (id: 10051) (name ''superEquipment'') (type (ref: 5)) (container true) (opposite (ref: 10061)) ) the code generated looks like this : superEquipment <MSEProperty: #superEquipment type: #SCAbstractEquipment opposite: #subEquipments> ^superEquipment should not it be like the following ? superEquipment <MSEProperty: #superEquipment type: #SCAbstractEquipment opposite: #subEquipments> <container> ^superEquipment It is pretty important because it allows the traversal of a model based on the containment of objects.
