Lack of clarity on .ecorediag and .ecore synchonisation [message #1064618] Thu, 20 June 2013 05:14 Go to next message

Hi, would appreciate a pointer to where the following topic is described or explained.

I use the New... other... Ecore Tools > Ecore diagram to create a class diagram, which also creates a corresponding .ecore metamodel file. When I update this diagram, the .ecore file is also updated.

However, I've had cases where I've deleted content from the model via the diagram (like a 'comprises' association), but there appears to be some legacy of the original association then left in the .ecore metamodel, even though it is removed from the .ecorediagram.

Is the way that the .ecore and the .ecorediagram synchonisation is explained somewhere? Is there some way I can force the .ecore model to be updated to be consistent with the .ecorediagram?

(My workspace is stored directly on a laptop drive, not on a network drive, so this is not any sort of file synchonisation problem).

Thanks.
Julian.

Hi Julian,

The Ecore diagram editor is non-canonical i.e. it supports displaying only a subset of an Ecore model. As such, deleting a graphical representation of an Ecore element (e.g. EClass) using the delete/backspace keys only removes it from the diagram. To delete an element from both the diagram and the underlying Ecore model you should right-click it and select "Delete from Model".

Regards,
Dimitris
