No notification after boolean undo

Anonymous
Not applicable
To reproduce:

1. Create a wall
2. Create a new wall that intersects the first (or just drag another wall in)
3. Move the original wall away from the area of intersection

ArchiCAD apparently triggers a boolean operation, subtracting from the new intersecting shape. But when you move the other shape away it exposes the cut but doesn't raise a notification. The only notification is on the shape you've moved.

ArchiCAD manages it OK. The wall is restored in the 3D view. And if you force a notification on the modified wall - such as by opening Selection Settings and clicking OK, the correct geometry is available. But the AddOn doesn't get notified even though the geometry has changed.
