Instance of FamixCppModel class did not understand #importingContextClass

[nkinesis]

I get the error message "Instance of FamixCppModel class did not understand #importingContextClass" when I follow these steps:

• Open Models Browser
• Import model from MSE or JSON file
• In the model type combo box, select "FamixCppModel"

I checked the Java and ST models, they have "importingContextClass" but Cpp does not have it for some reason.
