> emf uml2 implementation of EnumerationFacadeLogicImpl modifies the underlying
> meta object in handleGetMemberVariables
> ---------------------------------------------------------------------------------------------------------------------
>
> Key: UMLMETA-87
> URL: http://jira.andromda.org/browse/UMLMETA-87
> Project: UML Metafacades
> Type: Bug
> Environment: 3.3-SNAPSHOT
> Reporter: Marcio Silva
> Assignee: Wouter Zoons
> Attachments: patch.txt
>
> Using typeSafeEnumerations and UML2 Enumerations in the model results in java
> enum's that don't contain any enumeration literals.
> The cause can be traced to a call to retrieve the member variables on line 20
> of TypeSafeEnumeration.vsl
> #set ($hasMemberVariables = !(${enumeration.memberVariables.empty()}))
> The underlying call to EnumerationFacadeLogic.getMemberVariables() ends up
> emptying the underlying metaObjet's ownedLiterals collection through an
> incorrect application of CollectioUtils.filter()
> handleGetMemberVariables() has the following two defects:
> 1) the call below should be to getOwnedAttributes instead of getOwnedLiterals
> 85 final Collection variables = (this.metaObject instanceof
> Enumeration
> 86 ? ((Enumeration)this.metaObject).getOwnedLiterals()
> 87 : CollectionUtils.collect(this.getAttributes(),
> UmlUtilities.ELEMENT_TRANSFORMER));
> 2) The call to CollectionUtils.filter ends up filtering the underlying
> metaObject's ownedLiteral collection, removing all reference to the
> Enumeration's owned literals. If filtering is desired, it's best done on a
> copy of the Collection not the collection retrieved from metaObject.
> The same erroneous filtering occurs in handleGetLiterals it just ends up
> being side effect free as the evaluation method always returns true.
