Hi,
I am using uml2 and I have a problem with assigning a default value to an
inherited property.
In my uml model I have a class A with a property a. In a class B, which is
a child of A I would like to assign a default value for the property a. In
class B I use the same name for the property a.
When I try to generate the EMF model I get a warning "Discarded feature
'B::a' because it is a duplicate of inherited feature 'A::a'".
If I set the "Redefined Property" of B::a to point to A::a it is even
worse because I get an additional warning: "Feature 'B::a' should be
annotated as redefintion of feature 'A::a'".
Obviously when I generate a java code on the basis of my model the default
value is not assigned to the property a of class B.
Any idea how I could assign a default value to the property a of the class
B?
regards,
Szymon

Szymon,
I can't recall off-hand whether the templates support re-initializing the
field to a different default, but if they don't, I don't see why they
couldn't. If you open a Bugzilla request, we'll look into it.

Szymon,
If you set the option for redefined properties to "Process" instead of
"Report", you won't encounter those warnings, and you'll get the (limited)
support that the UML2 code generator provides for redefined properties.
