Error description

• In IBM Rational Software Architect (RSA), if you create a new
  message between two lifelines, one of which is a class with a
  realization relationship with an interface of the same name, the
  'Operation owner' drop down list will display the duplicate
  name, as the class and interface have the same name.
  
  The following steps reproduce the problem:
  
  1. Create a UML project and model
  
  2. Add a class to the model and call it 'Class1'
  
  3. Add an interfact to the model and call it 'Class1', so that
  it has the same name as the class
  
  4. Add a second class to the model and call it 'Class2'
  
  4. Add a realization relationship between the class and the
  interface
  
  5. Add a sequence diagram to the model
  
  6. Drop 'Class2' and 'Class1' onto the sequence diagram
  
  7. Draw a message from 'Class2' to 'Class1'
  
  8. Select to create a new operation
  
  Expected Result: In the 'Operation owner' drop-down list of the
  'Enter Operation name and owner' dialog box, you can distinguish
  between the class and the interface, even though the two have
  the same name.
  
  Actual Result: Because the class and interface have the same
  name, the 'Operation owner' value is duplicated in the list.
  You cannot distinguish between the class or interface.
  
  Workaround:
  Give the class and interface different names.

  ****************************************************************
  In a sequence diagram, when a new message is created between
  two lifelines, one of which is a class realizing an
  interface of the same name, the "Operation owner" drop down
  list will show duplicate names for the class and the
  interface.
  

Problem conclusion

• If a class and the interface that it realizes, have the same
  name in the drop down list, the names are now appended with
  the type name to differentiate between the classifiers.
