DataPortal.Create Error

When ever I try to do the "

Return DataPortal.Create(Of Company)(New Criteria(0, TypeID))"

I am getting the following "Server.DataPortalException" error message.

?ex.Message

"DataPortal.Create failed on the server"

?ex.InnerException

{"Object reference not set to an instance of an object."}

System.NullReferenceException: {"Object reference not set to an instance of an object."}

Data: {System.Collections.ListDictionaryInternal}

HelpLink: Nothing

InnerException: Nothing

Message: "Object reference not set to an instance of an object."

SouthSpawn:
Return DataPortal.Create(Of Company)(New Criteria(0, TypeID))

The Return statement above is correct. You just need to change the declaration of your DataPortal_Create.

From:
Protected Overrides Sub DataPortal_Create()
End Sub

To:
Protected Overloads Sub DataPortal_Create(ByVal criteria As Object)
End Sub

Also remove the <Csla.RunLocal()> attribute if you're hitting the database.
