When attempting to execute the Update command on an SQLAdapter object, I get the following error:

     'Variable Values at Time of Execution:
     'Me.Parent.Parent = DataSet Object
     'Me.TableName     = "tblUsers"
     'Me.Parent.Parent.Tables.Contains("tblUsers") = True
     objAdapter.Update(Me.Parent.Parent, Me.TableName)

System.InvalidOperationException: Update unable to find TableMapping['tblUsers'] or DataTable 'tblUsers'.

I am at a complete loss as to why I am getting this error. I would not be surprised if it's something simple that I overlooked, but darned if I can't seem to track this down. Any help would be appreciated...
