How to add an Artifact to an Activity Diagram [message #1714183]

I am able to add Artefact elements to an Activity diagram in the Model Explorer (using the New Child context menu), but they do not become visible in the diagram. I have tried to drag-and-drop from the Model Explorer to the diagram, but it has no effect.

How should I proceed to make Artefact elements visible?

Thank you.

Hi Luis,

If the Activity Diagram is not designed to display Artifacts, then you can't

Currently, only the ClassDiagram allows arbitrary elements to be displayed

Hi Luis,

as far as I know, Artefact modeling element is not part of Activity diagram concepts and that is the reason why Papyrus does not show it.
Some tools allow this kind of "mismatch" but not Papyrus that is quite good in conformance with the specification.

Artefact is a concept of deployment diagram. That is the kind of diagram you can use to see it.

Best regards
Raphaël

Indeed, the Model Explorer provides an action for creation of Artifacts
as nested classifiers. Because all Behaviors (such as Activity) are a
kind of Class, they can own nested classifiers. But, it doesn't make
sense for behaviors to have nested classifiers, does it? It seems to
me that there are many features of a Class that don't make sense for
Behaviors (they can be active and own a classifier-behavior, too!).

I think that's because the spec. says that "If a behavior doesn't have a context, then it is its own context". So it may have its own Structure, etc.
