Why do I receive an error when using Bus Objects in a Masked Subsystem in Simulink 6.0 (R14)?

I have a Masked Subsystem with a Bus Creator block. The properties of the bus are specified with a bus object in the base workspace. When I try to run the model I get the following error:

 Simulink.DataType object 'bs_pva_Obj' is not in scope from 'some_original_model/SOME_SYSTEM/Bus Creator'

This bug has been fixed for Release 14 SP1 (R14SP1). For previous releases, please read below for any possible workarounds:

This has been verified as a bug in the way that bus objects are handled in Simulink 6.0 (R14) .

Currently, to work around this issue, you can remove the mask from the Subsystem or use the Bus Object as a Mask Parameter.
