That setting only affects the generated code, bug given that no field
will be generated and only stubs that throw exceptions for the accessors
are generated, so that won't work without some hand written code.

Transient things in the serialization won't generally cause exceptions
in deserialization (except possibly in cases of bidirectional
references; I'm not sure).

They'll generally just be read into the model, but won't be written back
out again.

Amine,
You have to use generator adapters for that. Try installing the
Generator Adapter Example into your workspace for an example.

Hi,
I have defined a derived volatile attribute. Now I need to implement the
getter. By default, the EMF generator creates a method stub, and I have
to manually implement the body. In order to avoid trouble in case of
re-generation (actually, I'm using an Xtext post processor to add the
derived attribute, so "@generate not" is not working), I would like to
define the body of the getter in the model, similar to the body of an
operation (which can to be defined in an annotation). Is that possible?
Actually, I would like to simply add the body in the post processing
step, when I define the attribute.
Regards,
Jens

Jens,
The generator has methods like this
protected String getGetterBody()
{
EStructuralFeature eStructuralFeature = getEcoreFeature();
EAnnotation eAnnotation =
eStructuralFeature.getEAnnotation(GenModelPackage.eNS_URI);
return eAnnotation == null ? null :
(String)eAnnotation.getDetails().get("get");
}
that will extract the stub into the generated code.

Kosala,
The latest version of EMF supports generating a live validator that will
revalidate all the instrinct constraints in the model after each command
stack execution. It's possible to expression such constraints using
OCL; you can look at that project's documentation.

Hi Regent,
It's not an answer to your question, but perhaps this project would be
of your interest.

Régent,
I won't have time to look until later this week. Please open a bugzilla
with the details and I'll try to reproduce it and fix or redirect it as
appropriate.

Hello,
I have this issue: I want to upload my existing file-based resources to CDO server. These resources are contained in ResourceSet and have cross-document references. The URIs in the ResourceSet are file-based since the ResourceSet is loaded from my local hard drive. However, on the CDO server I need to have those URIs little bit differently structured. For exmaple instead of having
/project/content.xmi
I would like to have something like
/allprojects/project/content
Is there any simple way to achieve this?
Regards
Martin

The new "Resource Transfer Framework" is made for this purpose. With this framework the generic CDO UI supports drag and
drop of multiple files/folders between workspace, file system and repositories.
