Now trying to use this same approach on my production data using GUID type PK's and FK's, the Function ConvertValue in the ObjectConverter is throwing an error, saying that "The input value could not be converted to the output type."  

I looked through this code, and there doesn't seem to be an If statement for a GUID type.  Is this something that is just impossible at this time, or not doable all together, or am I just going about this the wrong way?

Thanks,
