How to drag object to sequence diagram as link?

[Wolfman]

Using EA 10.0.1004.
When I drag an object from a different package into a sequence diagram, an instance element is always created. I never get the Paste Element dialog box as I do when dragging into other types of diagrams, not even when I hold down Ctrl. Changing the value of Auto Instance in Options-Diagrams-Behaviour has no effect. I think this behaviour was introduced in one of the latest upgrades.

What should I do to make it possible to drag an object from another package into a sequence diagram as a link?

It does not make sense. So it's not possible. A lifeline is only valid in the context of a single SD. Therefore SDs should be placed in an Interaction element along with their lifelines.

I think later versions of v10 allow it (even though it's a bad idea)

It is also possible in 10.0.1004, it just a bit harder.
Here's what you need to do:

- Open a class diagram
- Ctrl-Drag a class onto the diagram
- Choose link and check both options below "Options" button.
- Go back to the sequence diagram and simply drag the element onto the diagram. It should now create a link rather then an instance.

Thanks. I see all of your points but in this particular case it is what I wanted.

@Geert: Thank you very much for the instructions. Good that it is indeed possible.
