I apologize in advance for the vagueness of this request but I'm pretty lost.
I have these entities FamilyMembers / Patient / Person ( this three are in hiearchy of the Party Entity ) Family (which has FamilyMembers) FamilyGroup (which has many Families) I need to show the family group from the patient.. only if he belongs to a family and only if this family belongs to a group I tried to follow this discussion https://groups.google.com/forum/#!searchin/tryton/$20domain/tryton/yUIevSXB_R8/VJhFdZW2hAsJ but I'm really confused of where to put what. I guess I have to use field.Function in FamilyMember but what type of field should be inside it? Thanks. Mariano
