adding dynamic properties to static objects [message #420222]

Hi,

As mentioned above, my goal is to add dynamically generated EAttributes or
EReferences to existing meta objects which were generated statically from
an ecore file. However, it seems that this feature is not supported by EMF
(it results in an StackOverflow error in BasicEObjectImpl).
Is there maybe another possibility to implement a method where the user
can enrich arbitrary existing meta elements with custom EAttribute-like
"properties")

Regards,
Chris

If you set up the instance the way it would be set up if you defined a
model with XML Schema wildcards then you'd be able to use features from
documents root classes of other packages to augment the regular
features. The AnyType from the XMLTypePackage is an example of this and
this article will help:
