I do a reverse engineering for class diagrams dragging the classes and dopping it into the uml model. They get created fine without error. Then i go to the new class diagram and drop second set of classes they get created fine without any errors.
When i close the umldi tab and after some time i try to open the umldi file it is always giving me following error.


BELOW ERROR DOESNOT MAKE SENSE SINCE I HAVE BOTH THE .uml and .umldi FILES CREATED IN THE SAME FOLDER. LET ME KNOW WHY IS THIS HAPPENING IS IT A BUG IN MYECLIPSE?


Could not open the editor: Model file /GatewaySDK/gatewaysdk_uml_model.uml could not be located

sadashiv.borkar,

Please share the installation details with us from the menu MyEclipse > Installation Summary > Installation details.
Can you answer some questions for me?

1. Are you using the UML1 or UML2 model?
2. Can you switch the workspace, create a new project and check if the issue persists?

Let us know how it works for you.
