FUML12 — ReclassifyObjectAction does not preserve structural feature values

  • Key: FUML12-7
  • Legacy Issue Number: 18279
  • Status: closed  
  • Source: Model Driven Solutions ( Mr. Ed Seidewitz)
  • Summary:

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

    Subclause: 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.

  • Disposition: Resolved — FUML 1.2
  • Disposition Summary:

    Update ReclassifyObjectActionActivation

    Agreed. In addition, the semantics for a reclassify object action should ensure that private superclass attributes are removed or initialized as appropriate, consistent with the resolution to issue FUML12-20.
