Error and valid results are usually not the same. If you could give the code snippet, where the cast occurs or at least the call.

This obviously happens in the class HIADataPortal - which is not a part of CSLA.

It seems lke you have implemented your own HIADataPortal and there is a bug in this class - NOT CSLA. .
