Issue 18279: ReclassifyObjectAction does not preserve structural feature values (fuml-rtf)
Source: Model Driven Solutions (Mr. Ed Seidewitz, ed-s(at)modeldriven.com)

Severity: 
Summary: Specification: Semantics of a Foundational Subset for Executable UML Models (fUML), v1.1 (ptc/2012-10-18)

Subclause: 8.6.4.2.5 ReclassifyObjectActionActivation

 

The UML 2.4.1 specification says, in Subclause 11.3.39, under the Semantics for ReclassifyObjectAction, that "'New' classifiers replace existing classifiers in an atomic step, so that structural feature values and links are not lost during the reclassification, when the 'old' and 'new' classifiers have structural features and associations in common." However, the behavior specified in ReclassifyObjectActionActivation does not act this way. Instead, all feature values for old classifiers are removed before the feature values for new classifiers are added, so any values for common structural features are lost.
