I have 2 different perspectives and in of the perspective i do not want to allow the user to be able to select any element on the editor manually. Could this be achieved in any way.

Hello sowmya,

Try to remove EditPolicy.PRIMARY_DRAG_ROLE EditPolicy from corresponding
diagram elements (EditParts).

Hello Alex ,

I added "removeEditPolicy(EditPolicy.PRIMARY_DRAG_ROLE);" in corresponding editpart , but still I am able to select the element and I am able to drag as well.

Best Regards,

I faced a similar issue and here is the workaround I used:
I couldn't successfully override the PRIMARY_DRAG_ROLE from any EditPolicyProvider, whatever its priority is. It seems that this role is set up on elements by the container's XYLayoutPolicy, in the createChildEditPolicy() method.
Then it is possible to override the container's EditPolicy by Overriding the LAYOUT_ROLE on containers and providing a custom XYLayoutPolicy with a custom createChildEditPolicy method.

I used a ResizableShapeEditPolicy, with some method overriden (showSelection, getMoveCommand...) and it helped me.
