Why does an error occur when I update a diagram that uses bus objects and Configurable Subsystems in Simulink 6.1 (R14SP1)?

I have created a Configurable Subsystem library that expects a bus signal as the input. This bus object is defined in the MATLAB workspace. When I copy the Configurable Subsystem block into a new model that does not define the bus and update the diagram, an error similar to the following occurs:

 Selected signal 'sig1' in 'untitled/Configurable Subsystem/System One/Bus Selector' is not part of the bus entering the Bus Selector

This error message is expected since the Bus Selector inside the Configurable Subsystem expects the bus specified by the bus object.

To avoid receiving this error, use a block such as a Bus Creator or an Inport, in the new model to generate the appropriate bus and feed the Configurable Subsystem.
