Working with annotations [message #635990]

Hi,

I modeled an EClass (e.g. 'Car') and annotated it with an annotation.
The annotation has a containment reference to an EObject (e.g. an
'Config' element) described by a model provided via the package registry.

After serializing my Model with the 'Car' EClass the XML file contains
all the content I excpect: The 'Car' EClass, the annotaion and the
'Config' EObject contained in the annotaion. So far, so good.

I ran into problems when I tried to access the content of the annotaion
at runtime. It's empty. :-(

EAnnotation eAnnotation =
CarPackage.eINSTANCE.getCar().getEAnnotation("source");
eAnnotation.getContents().isEmpty(); // returns true

Is this generally not possible? Or is there something I have to consider
when working with annotations?

Thanks in advance.

Cheers,
Bernd

Bernd,

If you need such things at runtime, you'll have to specify Initialize by
Loading on the GenPackage.
