Round-trip for update and delete operations does not work

I use VP Standart Edition v10.0 integrated with Eclipse Helios. I Instant Reverse UML diagrams from the existing source code and then use Configure Round-trip option. However, the following scenarious do not work for me:

  • update existing operation of a class on generated UML Class Diagram and use Update Code option (changes are not reflected in the source code);
  • delete existing operation of a class on generated UML Class Diagram and use Update Code option (changes are not reflected in the source code);

Creating a new operation in existing class of generated Class Diagram and Updating Code does work, i.e. the changes are reflected int he source code.

Thank you,
