If a BindableInstance has a type and a represented feature, the type of the instance must be compatible with the type of this feature.


A part can represent an Attribute, an AssociationEnd or a Port.

  • In the case of an Attribute or a Port, the type of the BindableInstance must be the same type as the Attribute or the Port.
  • If it represents an AssociationEnd, it must be the same type as the owner of one of the Associations’s other AssociationEnds.


Change the type of your instance, or change which model element it represents.
