Hi Saif,
The id objects need to be serializable. Teneo uses the SerializableDynamicEObjectImpl for this (a Teneo class). But
maybe in your code you create DynamicEObjectImpl and set those objects as the id of another DynamicEObjectImpl. I
guess/maybe using the Teneo SerializableDynamicEObjectImpl would solve your problem.
Btw, I am also quite interested to get some form of Dynamic model support in Texo. The thing I am uncertain about is how
to generate the mapping dynamically (I would like to stick to jpa and not use eclipselink/hibernate specifics).

Hi Saif,
Texo uses EcoreUtil.create which does this:
return eClass.getEPackage().getEFactoryInstance().create(eClass);
I guess to solve this you can create your own EFactory implementation, delegating everything to another efactory
instance, except for the create method you implement to create a SerializableDynamicEObjectImpl for the eclasses in
question. Then you have to set your EFactory implementation in the dynamic epackage you created (setEFactoryInstance)
The delegate efactory can be the efactory present in the epackage already.
