APAR status

• Closed as program error.

Error description

• Environment:
  RSA 8.5.1
  Windows
  
  Reproducible:
  Yest
  
  Description of problem:
  After you moved a guard condition of one combined fragment to
  another in a sequence diagram in Rational Software Architect
  (RSA) 7.5.x, the diagram won't open in RSA 8.5.1, and you
  receive the following error:
  Could not open the editor:
  com.ibm.xtools.uml.ui.diagrams.sequence.internal.editparts.Inter
  actionOperandEditPart
  incompatible with
  com.ibm.xtools.uml.ui.diagrams.sequence.internal.editparts.Combi
  nedFragmentEditPart
  
  Steps to reproduce:
  1. Create a model in RSA 7.5.x
  2. Create a sequence diagram with combined fragments.
  3. Move a guard condition of one combined fragment to another
  4. Open the model in RSA 8.5.1
  5. Try to open the sequence diagram
  6. Notice the error message.
  
  Workaround:
  The only workaround is to delete the diagram and to recreate a
  canonical one. However, with this workaround you will lose
  layout and comments.

  ****************************************************************
  When the customer's diagram from 7.5.x is opened in RSA
  8.5.x, a classcast exception is thrown. Could not open the
  editor:
  com.ibm.xtools.uml.ui.diagrams.sequence.internal.editparts.I
  nteractionOperandEditPart incompatible with
  com.ibm.xtools.uml.ui.diagrams.sequence.internal.editparts.C
  ombinedFragmentEditPart
  

Problem conclusion

• The actual issue of the classcast exception, when the
  diagram from 7.5.x is opened in Rational Software Architect
  8.5.x, has been fixed. To prevent the stereotype migration
  popup dialog from hanging the product when 7.5.x customer's
  diagram is opened in 8.5.5.1, the user has to uncheck "Frame
  always fits contents" prefernce in Modeling ? UML Diagrams
  only for the first time when the diagram is opened. Once the
  diagram is migrated, he can check the preference and there
  wouldn't be additional issues when reopening the diagram.
