After exporting the contents of an RRC project attempted to run a 'requirements composer artifact transfom' transformation within RSA. Although the 'validate configuration' completed successfully the artifact transfom aborted reported:

Transformation execution status.
java.lang.ClassCastException: com.ibm.rdm.ba.usecasecontext.impl.SystemBoundaryImpl incompatible with com.ibm.rdm.ba.usecasecontext.UsecaseRef

Does the problem lie with the RRC artifacts of the RSA setup?

Thanks
