Yes, this is correct. It isn't as simple as just making the properties
visible. Not all of the internal actions of the InternalDataset would
trigger the necessary TDataset buffer refresing that is required. I presume
you have done some use-case testing and found this to be the case.

Thanks for taking some time on this!
