Hi all,

I have a problem with VS 2005 and MM .NET regarding a stored procedure. I've added the code to the responsible entity, but somehow I always get the following error:

Procedure or function 'SUBSTANCESelectBySubGroupFK' expects parameter '@GROUP_ID', which was not supplied.

Here is the code in my entity:

        public mmBindingList<SUBSTANCEEntity> GetSubsBySubGroupFK(int? groupID)
        {
            mmBindingList<SUBSTANCEEntity> SubsList;

            if (groupID != null)
            {
                SubsList = this.GetEntityList("SUBSTANCESelectBySubGroupFK");
                    this.CreateParameter("@GROUP_ID", groupID);
            }
            else
            {
                this.GetEmptyDataSet();
                SubsList = new mmBindingList<SUBSTANCEEntity>();
            }
            return SubsList;
            //return null;
        }

And here is the stored procedure:

set ANSI_NULLS ON
set QUOTED_IDENTIFIER ON
GO


ALTER PROCEDURE [dbo].[SUBSTANCESelectBySubGroupFK]
(
	@GROUP_ID int
)
AS
	SET NOCOUNT ON;
	SELECT [COMPANY_ID],
		[CRE_DATE],
		[CRE_USER],
		[GROUP_ID],
		[MOD_DATE],
		[MOD_USER],
		[SUBSTANCE],
		[SUBSTANCE_ID] 
	FROM [dbo].[SUBSTANCE]
	WHERE 
		([GROUP_ID] = @GROUP_ID)

Am I missing something? It works just fine with anothere entity/stored procedure, which is pretty similar to that. The parameter is not empty, but somehow it does not get passed on to the stored procedure.
Thanks!
