Description

Build Identifier: 20100617-1415

Trying to get the ordinal for an enum using EnumType.allInstances()->asSequence()->indexOf(...) does not compute in the OCL Interpreter Console (empty result). It does for other types.\ See http://www.eclipse.org/forums/index.php?t=msg&th=173931&start=0&S=79151d79cb376a55a724e7980d46d1c7 for details.

Reproducible: Always

Steps to Reproduce:

1. Define enum EnumType with at least Literal as element
2. Compute EnumType.allInstances()->asSequence()->indexOf(EnumType::Literal)

CollectionKind.allInstances()->asSequence()->indexOf(CollectionKind::Set) works in the pivot evaluator.

I looked at changing the modelled:

type Enumeration conformsTo OclAny {\ static operation allInstances() : Set;\ }

to OrderedSet, but now I realise that this is a total specification fudge corresponding to the implementation fudge that was required to make it 'work'.

An enumeration literal is an EnumerationLiteral not an Enumeration (cf a property is a Property not a Class).

CollectionKind.ownedLiteral->indexOf(CollectionKind::Set)

also works and is semantically sensible.

I think that Enumeration::allInstances() should be retracted.

WONTFIX: Bugzilla only remains open to raise an OMG Issue.
