XMI Export from Papyrus to Enterprise Architect: Do stereotypes and diagram layout survive round‑trip?
Goal Validate that a UML model exported as XMI from Eclipse Papyrus can be imported into Sparx Enterprise Architect without losing applied stereotypes, tagged values, or diagram layout information. Constraints & Uncertainty The XMI header specifies the UML metamodel version; a mismatch between Papyrus (e.g., UML 2.5) and Enterprise Architect may cause el
Multiplicity Constraint Violation in Association Class Definitions
In UML class diagrams, an Association Class is designed to hold properties that belong to the relationship between two entities rather than the entities themselves. According to the specification, an Association Class represents a unique link between participating instances. A conflict arises when attempting to define multiplicity constraints on the Associat
InterruptibleActivityRegion missing default timeout for interrupting edges
Goal Define a portable default timeout that governs how long an interrupting edge may wait before forcing cancellation of an InterruptibleActivityRegion. Constraints and uncertainty The UML 2.x specification describes InterruptibleActivityRegion and interrupting edges but does not prescribe a default timeout duration. AcceptEventAction can consume time event
