Properties: Redefinition: Display in EA 9.0

[Michael Hafner]

Dear all,
is there any possibility to display the redefinition of a property on a diagram?

I think, documentation of an earlier version (7.*?) had it that attributes with identical names would "be merged" somehow in this case:


Att_01 isAttributeOfClass Cls_01 &&


Att_01 isAttributeOfClass Cls_02 &&


Cls_02 isSubClassOf Cls_01


(Cls_02.Att_01 being regarded as a redefinition of Cls_01.Att_01)

However, the feature did not seem to work at the time, and obviously has been discarded. According to UML 2.3 (http://www.omg.org/spec/UML/2.3/Superstructure/PDF/), redefinition should be stated thus:

‘redefines’ <property-name>

So that, in the context of Cls_02,


Att_01 {redefines Att_01}

EA has a very efficient way to model redefinition, but is there a way  to display it  as well - ?

Best,

Michael

I know it works correctly for associations, but I've never tried it on attributes.

It's a little confusing:

1. Associations: Via tabs Association Properties > Source|Target Role > Qualifiers, you reach a tab, Detail, which is about redefinition, however, all the controls are disabled. No redefinition is shown, even if it's there. You have to use the context menu Advanced - always a good bet - and select Association Specialization. Now you can assign a redefinition, albeit only one. But it works, like you said.


2. Attributes: Attribute Properties > Detail. Here, the controls work, you can even assign multiple redefinitions. But they aren't shown anywhere, and I haven'd discovered any visibility option so far.
