Hello there,
For element creation tools, specifically for edge creation, there is always two variables: sourceView and targetView that refers to the graphical element of, respectively, source and target. I am navigating through these elements, but I would like to, at some point, access the eObject it represents.
According to some forum topics and tutorials, there is a "target" field or method that retrieves this element, but as I try to use it, Sirius tells me there is no field (target) or method (target(), getTarget()). I believe I have to cast to a specific type (using oclAsType method) to be able to access it, but which type?
My expression, for now:
[sourceView.eContainer().eContainer().getTarget()/], whereas sourceView.eContainer().eContainer() is the diagram itself.
@Edit
For my specific case, I cannot navigate using source and target variables, since their eContainer() is an eObject that is part of another diagram.

If you are sure about the expected type you can cast (with oclAsType)
the eContainer() result to DSemanticDecorator which is the interface for
all DDiagramElements with a semantic target.
