Stereotype: Default value setting on a multi-valued enumeration [message #1755030] Mon, 27 February 2017 08:50 Go to next message

Hallo,

I have defined an enumeration typed attribute in a stereotype which has a multiplicity of [1..3]. A single literal of the enumeration is defined as the default value; this is done via InstanceValue.

Unfortunately the default value (defined in the profile) does not appear in the
attributes of a class in a model which has the profile applied; the set is empty (settingActor: SettingActor [1..3] = []).

Did I define the default value in the profile in the wrong way?

Thank you for your help.

Regards
Bernd

I have tested this scenario and I remark this problem when the property of the stereotype has an upper value greater than 1.
To be correct the default value must be a collection with 3 instanceValues, but there is no construction in UML to express a collection of InstanceValue... This is a lack of UML.
Best regards,
Patrick

Dear Bernd,

I guess when you say that the default value does not appear in the attributes of a class, you actually mean that it does not get assigned to the multivalued stereotype attribute typed with the enumeration.

I confirm that the assignment does not get done. This is not specific to enumerations, but would be the same for an integer value assigned to a multi-valued property. The problem is the combination of a collection with a single default value: semantically, it is not clear how many elements should be created for a multi-valued attribute. So, while I am not sure, I don't think that it is possible.

Hi

It could be possible using an OCL expression - an OpaqueExpression with an OCL-valued body.

If you want to have a purer AST, then an ExpressionInOCL is a more powerful ValueSpecification, but there is no UML2/Papyrus tooling support for hybrid UML+OCL ASTs.

Beware. A bad bug with OCL support for Enumeration-valued InstanceValues was fixed about six months ago.

Regards

Ed Willink
