Dynamically extending a non-dynamic abstract EClass [message #1105126]

Hi,

I do have an EPackage APackage, which contains an abstract class A. For
this package I have code generated.

Now, at runtime I create a package with another class which extends the
abstract class A from the other package.

Now I try to create an instance for this, but it throws an exception in
APackageFactory: 'The class A is not a valid classifier'

I thought (optimistically as always with EMF, it can do anything ...)
that this should be possible, but maybe not?

Thanks for comments,
Felix

Found something here, http://www.eclipse.org/forums/index.php/t/128121/
and here https://bugs.eclipse.org/bugs/show_bug.cgi?id=105931

So not possible. Well, Eike Stepper wanted it some time, at least I'm
not completely crazy (Or maybe I'm just as crazy as him :p)
