Entity Framework Will Not Preserve Relationships

Question

I have the following situation:

role.Permissions.Add(permission);
objectContext.SaveChanges();

When I look at the Roles_Permissions relationship table now, there is no new added permission for the role. It only retains a new relationship when I have the context of the object. Am I doing something wrong or does the SaveChanges call not save the changes in the relationship sets?

You can verify that your permission object is known to your object by running the following line of code:

objectContext.AddObject("Permissions", permission);
