.. is producing a runtime System.NullReferenceException: Object reference not set to an instance of an object.

I believe there's nothing wrong with my syntax:

Dim courseLocationsDataRelation As New DataRelation("theName", dataSet.Tables("PRODUCT_EDUCATION").Columns("PRODUCT_ID"), dataSet.Tables("PRODUCT").Columns("PRODUCT_ID"))

I have tried adding qualifiers to the tables name like so: [PDEV].[dbo].[PRODUCT_EDUCATION] but this doesn't make things better.

I'm clueless of where to look at for what's causing the failure of the DataRelation instanciating.  I've tried intentionally introducing a wrong table name, to see if it would trigger a more explicit message, but no.. only the same indication that the object refuses to instanciate.
