Description Dennis Hendriks CLA 2016-05-04 05:45:09 EDT 
Steps to reproduce:

1) Create an EMF project with an Ecore model.
2) Create a class diagram for the Ecore model.
3) Add some classes to the Ecore model.
4) Observe how the diagram overview in the Outline view is OK.
5) Move the classes to be positioned negatively relative to the diagram origin.
6) Observe how the diagram overview no longer reflects the visible part of the diagram editor.

It appears the negative offset with respect to the diagram origin is not taken int account when painting the diagram overview in the Outline view. As a result of this, the overview is drawn too much to the right/below. This effect is more clearly visible when only moving the classes a little bit, then moving them again a little bit, etc, until they are completely to the negative part.

Empty outline with negative relative move

Example(NegativeRelativePosition.zip) to reproduce problem more quickly. 

Open NegativeRelativePosition Diagram.
Select Test1 and Test2 and move these to left top corner until they are not visible in the outline.

Dennis, 

For information you can use Ctrl + & to reset diagram origin as explain in the documentation: http://www.eclipse.org/sirius/doc/user/diagrams/Diagrams.html#ResetDiagramorContainerOrigin

Thanks, that's a quick and useful workaround.

But still, the bug should be fixed at some point, I think.
