The precondition of OperationAction and PopupMenu VSM elements are
Collection<DSemanticDecorator>, PopupMenu, IDiagramCommandFactory,
EditPart, Point) and
Collection<DSemanticDecorator>, EObject, IInterpreter).
To hide your menu (PopupMenu) or just a menu entry (OperationAction,
ExternalJavaAction, ExternalJavaActionCall), you just have to complete
For example, in a DiagramDescription on ecore used to represent EPackage
and EClass element, you could put [thisEObject.oclIsKindOf(EPackage)/]
to enable your menu only when an EPackage is selected.
The evaluation context will be the first selected semantic element, you
also have access to the "views" variable, which references the selected
views (allows to retrieve all selected semantic elements, if required,
with the DSemanticDecorator.target EReference).
Additional note: if a popup menu is empty or if all its items are
disabled, it will not be displayed.
