Adding a hyperlink to an Activity diagram creates a new Activity

[Geert Bellekens]

I have two activity diagrams (diagram1 and diagram2)
When I drag diagram1 onto diagram2 and select Hyperlink, EA creates a new Activity, with the name diagram1 on my diagram2.

This does not happen when either diagram1, or diagram2 is not an Activity Diagram.

I don't know what the original purpose of this feature was, but it is obviously broken.

Workaround: drag diagram1 onto another type of diagram (say class diagram) as Hyperlink. Then copy the hyperlink and paste it onto diagram2

I think it's a hang-over from early UML where the diagram IS the activity.  (like "a named association end IS an attribute")

In V14 or V15  (I do not remember) Sparx programmed some magic but senseless assumptions when you drag and drop something related to activities.
Most of those silly features disappear in V15.1 but some might buzz around.

There is an option to switch that off: Preferences | Behavior | Use Automatic SubActivities

Thanks, that seems to do the trick.
I still believe this feature is fundamentally broken and would better be removed altogether.

For the very least the default for this setting should be off.
