I've actually just found a solution for the main issue. Now I'm just left with the same issue that Walid has. I'll post what I've had to do in my other thread.

Will do.

I'm not sure if they're actually the same issue though. I have to look into it again since it's been a while.

This was one of the issues I was having a few months back.

Glad it's getting fixed. Can you update us when you know if it's going to be in the next version?

Hi Walid;

Sorry for the delayed reply. Yes, this is a bug and I have a filed a bug report for it. It should (but no guarantee) be fixed in the next release.

Hi Walid;

I was able to reproduce your issue but let me clarify this first with a senior engineer and get back to you.

I'm trying to implement a sandbox editor for an entity having an n-n relation and have some troubles when I import the modified (and committed) entity back to the original manager.
For example, lets say we have Users (Administrator, User1, User2) and Roles (Admins, Readers,...).
A User has n-roles (User.Roles) ex User1.Roles = {Admins, Readers}, the entity relation is called UsersInRoles
After editing the existing user and removing some roles (importing it in a new EM then User1.Roles.Remove(Admins)) , re-importing it back (with a correct EntityGraph collection and OverrideChanges merge strategy) to the original EntityManager, leaves the User1.Roles collection untouched, the removed role Admins still remains in the Roles collection. If I refresh the original EM reloaded User has the correct roles.
Is it a limitation of DevForce or a bug ?
Sample Code :
...
public User ImportUser(User user, EntityManager manager){
...
var spans = new List<EntitySpan>() {new EntitySpan(typeof(User), EntityRelations.UsersInRoles)};
manager.ImportEntities(user.EntityAspect.EntityManager.FindEntityGraph(new object[] {user}, spans, EntityState.AllButDetached));
return = (User)manager.FindEntity(user.EntityAspect.EntityKey);
}
...
var sandboxEM = new MyEntityManager();
var sandboxUser = ImportUser(editingUser, sandboxEM);
...
sandboxUser.Roles.Remove(AdminRole);
...
sandboxEM.SaveChangesAsync(...);
...
ImportUser(sandboxUser, originalEM);
...
editingUser.Roles contains AdminRole !!!!
Thanks,
