Hi Alex,

I finally managed to make it work! Thank you very much for your help, I 
would not have succeeded without it.
I'll describe how I did it in the steps shown below. As you can see, some 
steps of my previous message are unnecessary (I'll try to make a GMF 
Recipe):

(i) make sure that both derivedCAttribute and BAttribute have the property 
"Notify" set to true in the genmodel file. Also, derivedCAttribute should 
have the properties "derived" and "volatile" set to true in the ecore file;

(ii) implement the method getDerivedCAttribute() in CImpl.java:
public String getDerivedCAttribute() {
if (getCtoB() != null) {
return getCtoB().getBAttribute();
else
return "";
}

(iii) implement the method setDerivedCAttribute(String newCAttribute) in 
CImpl.java, making a call to eNotify: public void 
setDerivedCAttribute(String newCAttribute) {
if (eNotificationRequired())
eNotify(new ENotificationImpl(this, Notification.SET, 
???Package.C__DERIVEDCATTRIBUTE, getDerivedCAttribute(), newCAttribute));
}

(iv) modify setBAttribute(String newBAttribute) in BImpl.java in order to 
call the implementation of the method setDerivedCAttribute:
public void setBAttribute(String newBAttribute) {
if (getBtoC() != null)
getBtoC().setDerivedCAttribute(newBAttribute);
String oldBAttribute = BAttribute;
BAttribute = newBAttribute;
if (eNotificationRequired())
eNotify(new ENotificationImpl(this, Notification.SET, 
???Package.B__BATTRIBUTE, oldBAttribute, BAttribute));
}

Thank you very much for your help!
