I almost get the sense that multiple inheritance is involved.  I.e., I 
think you are telling me that RoleSet inherits from Role, right?  It's 
important to realize that Java doesn't not support multiple inheritance 
of classes.  So the Impl class that implements RoleSet might not inherit 
from the Impl class that implements Role.  After all, if it inherits 
from two unrelated model classes A and B, while RoleSet will be an 
instance of A and of B, RoleSetImpl will inherit from either AImpl or 
BImpl, but not both.  In any case, you are telling me you can list all 
the Role instances but none indicated that instanceof RoleSet is true.  
That seems to imply to me that none of the Role instances are RoleSets; 
Java doesn't tend to lie abut such things.

This is like asking, why can I find A but I can find B?   How would I know?

It sounds to my like an unresolved proxy.  Does EObject.eIsProxy return 
true for them?   If you have unresolved proxy problems, which also 
sounds like a likely issue, it's most likely caused by not using an 
appropriate absolute URI to load the initial resolves.  Relative URIs 
within the serialization are resolved against the URI used to load the 
resource (just like in .html pages in a browser).  Does the .xmi contain 
href="" attributes?

Most projects ship with an SDK that includes the source code.  It's 
certainly in CVS...
