PM69298: INHERITANCE RELATIONSHIPS NOT DISPLAYED ON CLASS DIAGRAMS (C++)

APAR status

• Closed as program error.

Error description

• Environment:
  - Microsoft Windows
      - Product: RSA 8.5
  
  Reproducible: Y
  
  Description of problem:
  
  Inheritance relations of C++ classes that are inside a namespace
  are not displayed properly in a class diagram (after they have
  been dragged and dropped there for instance).
  
  In the property view of the children classes, in the 'Super
  class' table the green 'C' icon appears, but the 'Super Class'
  and 'Visibility' columns are empty. When the children classes
  explicitly specify the namespace of their parents, the problem
  doesn?t occur.
  
  The problem only happens when the class diagram is created using
  class from source. When converting the C++ classes to UML and
  then creating the class diagram from the model, the problem
  doesn?t appear.
  
  Steps to reproduce
  
  1) Create a class containing the same code as case 2 or case 4
  below.
  
  2) Drag all three classes on a class diagram.
  
  3) Notice that the inheritance relationship isn?t displayed and
  that in the property view the super class of the children isn?t
  displayed properly.
  
  // Case 1: Works properly
  class Base{};
  class Child1 : public Base{};
  class Child2 : public Base{};
  
  // Case 2: Base class is not found
  namespace NS1
  {
  class Base2{};
  class Child21 : public Base2{};
  class Child22 : public Base2{};
  }
  
  // Case 2: Works properly
  namespace NS2
  {
  class Base3{};
  class Child31 : public NS2::Base3{};
  class Child32 : public NS2::Base3{};
  }
  
  // Case 2: Base class is not found
  namespace NS3
  {
  class Base4{};
  }
  using namespace NS3;
  class Child41 : public Base4{};
  class Child42 : public Base4{};
  
  
  Workaround
  
  Create a transformation from the C++ to UML. Then drag the
  model?s elements to a class diagram. The inheritance
  relationships in the diagram are properly displayed.

  Generalizations are not shown on the C++ class diagram if a
  class is under a namespace.
  

Problem conclusion

• Generalizations are now shown on the C++ class diagram even
  if the class is under a namespace.
