Sample project to reproduce

With the Validation layer, the tooltip associated with object is someting like

> ERROR : The required feature 'eAttributeType' of 'org.eclipse.emf.ecore.impl.EAttributeImpl@33cd31cf{platform:/resource/EcoreToolsSample/My.ecore#//C1/requiredAttribute}' must be set

but the id of EObject changes at each Eclipse restart, so the diagram is dirty at each first opening after a restart of Eclipse. For example, after a restart, the same tooltip will be:

> ERROR : The required feature 'eAttributeType' of 'org.eclipse.emf.ecore.impl.EAttributeImpl@1dbef39d{platform:/resource/EcoreToolsSample/My.ecore#//C1/requiredAttribute}' must be set

Steps to reproduce:
* Import the project "EcoreToolsSample"
* Open the diagram "root class diagram"
* The diagram is dirty: KO
* Close the diagram.
* Open the diagram again, the diagram is not dirty: OK.
* Close the diagram.
* Restart eclipse
* Open the diagram, the diagram is dirty: KO.

Thanks for your feedback.

EMF iself compute this String with an explicit toString on the EObject.

I'll see if I can work-around this for the next build.
