CIF explorer crashes on models with function-typed discrete variables without an initial value

CIF model:

automaton a:
  disc func bool(bool) f2; // A dummy function is created for the default initial value.
  location:
    initial;
end

Running the CIF explorer on this model, with the 'enable report' option enabled, gives:

java.lang.NullPointerException: Cannot invoke "org.eclipse.escet.common.position.metamodel.position.PositionObject.eContainer()" because "parent" is null

The CIF explorer creates functions for the default values of function-typed variables, to store in the state objects. These objects have no name, and are not contained in the specification. Hence, getting their absolute name fails.
