The Model Editor displays the tl:TLModel or a portion of it as a diagram and allows you to edit it dynamically. Within the diagram itself, you can select the various objects by left-clicking on them.
The Model Editor toolbar includes a command to “relayout” the diagram; that is, the diagram’s display is updated by, for example, “optimizing” the positions of objects so that as few edges as possible cross each other.
Updating the diagram “discards” the old selection. Instead, no element is selected.
Test
Display a diagram, select an object, “re-layout” the diagram, and check whether the selection was retained.
