[mdt-papyrus.dev] [DeleteFromDiagramCommandHandler] Canonical Edge

[DAUSSY Arthur <arthur.daussy@xxxxxxxx>]

Hi everyone,

 I would like to have you opinion on a matter which impacts the DeleteFromDiagramCommandHandler.

 For the moment the implementation of this handler prevents to delete an edge which have for source and target canonical element.  I have to admit I don’t see any use case which it should be prevented.

 See in org.eclipse.papyrus.diagram.common.handlers.DeleteFromDiagramCommandHandler.isCanonical(List<IGraphicalEditPart>):

 

                                                           ….

            isCanonical = (!connection.isSemanticConnection() || (isCanonical(connection.getSource()) && isCanonical(connection.getTarget())));

                                                           ….

 

 I would like to know if it was a desired behaviour because this behaviour prevents me to delete in the activity diagram Object Flow.

 You can see the following use case:

 

I think in this case the Object Flow should be deleted (and/or hidden) so I would like to withdraw this condition. However don’t want to break any desired behaviour.

Does someone know any reason to keep this behaviour?

 

Regards
