Hello everybody.
first of all, EMF people say VE team have extended emf in order to
achieve the functionality i need, can you tell me if this is possible:
The requirement is this: lets say i have a .ecore file or a
programmaticlly made ecore model, whit my metamodel.
the applications starts and the user make several instances of the
metamodel and work with them, what happens if i need to change the
metamodel to reflect domain changes,
for example "now we need to know the persons father first name"
according to OO i will add an attribute to "person" but, emf doesnt
allowme this.
In other context this is known as "dynamic objects", is this possible to
archive this functionality using EMF with the extensions you have added?
The problems arises when i need to add a EStructuralFeature to a EClass,
if there are already model instances of the model, EMF don't let me add
new features.
