Hi

Can somebody help me with this?

I'm trying to copy a resource set of an object 'o' into 'rs'. But I got an
exception "cannot modify a resource set without a write transaction".

Object ‘o’ is an instance of class A in ecore model. Also in ecore model,
there are classes B and C. Between them, there are two references from B
to C. Each reference has its EOpposite value corresponds to one of the two
references from C to B. I think the exception occur because I do not know
how to set the value for these references in the ‘rs’ resource set.

Please show me how. Thanks.
