Hello everybody,
I have two classes A and B. Class A have two attributes: environment and
an attribute of type B (relation aggregation in GMF). Class B have an
attribute environment. Can anyone show me how to automatically set the
value of attribute environment of B equal the value of attribute
environment in A when user create an instance of B in A? Moreover, when
user change the value of environment in A, the value of environment in B
will change automatically and correspond to that in A. Thanks in advance!
Toan.

Hello Toan,

Looks like attribute environment in B should be derived and you can implement
corresponding logic in EMF-generated getEnvironment method then..
