Hi,
I need an efeature with a "type" Map<Object, EObject>. Unfortunately
defining a EMap<Object, EObject> datatype requires custom implementation of
(de)serializing the "value" EObject. And I do not want implement such
serialization as the object already is an EObject.
In principle I can make my EObject be able to identify itself with the
"key", but still I need a specific "unique" colletion (as feature value
holder).
That collection should ensure there is only one EObject with the same "key",
similar to set, but adding new EObject should replace the same "key" object.
Maybe somebody had similar issue?

How about using an EMap?

The serialization of EJavaObject isn't human readable so that's going to
be kind of yucky too...
