EMF Code generation from UML2 model fails [message #477841]

Hi,

problems don't stop :) Currently, i try to convert a UML2 model (with union
and subset) into a valid Ecore file. It contains an ownership relationship,
similar to the owner/ownedElements from the UML::Class::Kernel::Element.

ModelElement (EClass)
owner (EReference): changeable, non-transient, non-volatile, non-derived
ownedElements (EReference): changeable, non-transient, non-volatile,
non-derived

These both references are opposites. The problem is, that no attribute
ownedElements is generated into the ModelElement class. All the successor
methods are defined, but they produce a Syntax error, because of that
missing attributes. I can fullfill the missing attriibute by hand, but i
think, this is not the best way to handle such a problem?

Thx
TImothy

Hi Timothy,

Do you have a sample .uml model with .genmodel that I can use to reproduce
what you are seeing?
There may be some incompatible combination of properties that produce an
error.
Please raise a bugzilla if this is an issue in the UML2 project itself.

Cheers,
- James.

Dear James,

yes, it was a problem in the model. I've tried the same with a simple model
and it works.
But one question concerning the Union/Subset-List-Types of the UML2
codegenerator.

After creating an Ecore out of a really simple UML model, the Ecore was
annotated with some union/subsets-Annotations. So far so good. But after
code generation only the uniosn-Annotations resultng in a
DerivedUnionEObjectList-Type. All the subsets-relationships are treated as
ordinary EMF-List. I'm pretty sure, that i got him work, but currently,
either wich input i provide, it never produces these uml2 specific types.

I'm really confused...

Thx
Timothy

Timothy,

Depending on the multiplicities of your subset/superset properties, you may
or may not see the subset/superset lists being used by generated code. If
you attach a sample model that you think is problematic, we'll take a
look...
