I guess there’s a small mistake right here :

// 2. Use case – Create an observable for a nested attribute
public IObservableValue uc2(CommitterShip c) {
IEMFValueProperty prop = EMFProperties.value(
FeaturePath.fromList(
ProjectPackage.Literals.COMMITTER_SHIP__PERSON,
ProjectPackage.Literals.PERSON__LASTNAME
)
);
return prop.observe(p);
}

the return should be : return prop.observe(c); instead of return prop.observe(p);

Thanks

// 2. Use case – observe the nested list
// The list of all subprojects of the projects parent
public IObservableList uc2(Project p) {
IEMFListProperty prop = EMFProperties.list(
FeaturePath.formList(
ProjectPackage.Literals.PROJECT__PROJECT,
ProjectPackage.Literals.PROJECT__SUBPROJECTS
)
);
return prop.observe(p);
}
you are talking of obsevring subproject or PARENT project so the feature path should be
FeaturePath.formList(
ProjectPackage.Literals.PROJECT__PARENT, ///and not PROJECT
ProjectPackage.Literals.PROJECT__SUBPROJECTS
)
I think.
Anyway this is great post.
Thanks.

Looking forward to the rest of the installments!
