llblgen 2.6 built 10/16/2008
dotnet 2.0


Hi
My program was working flawlessly in llblgen 2.0. After I converted to llblgen 2.6 I got error. Below are the error message and source code (that I suspect where the error comes from). As you can see in the error message, the NumberOfError parameter seemed to get built wrongly in version 2.6 of llblgen.

Please advice. Thanks.

The trouble is solved. However I ran into another problem that I have no idea what the cause is. I suspect that the cause of the error has to do with llblgen v2.6

Here's the error detail

Exception is thrown whenever the pageNumber is greater than 1. Note that when pageNumber equals 1 then there's no exception thrown.

        public int NumberOfBills
        {
            get
            {
                return (int)this[_parent.NumberOfBillsColumn];
            }
        }
        ///// <summary>Gets / sets the value of the TypedList field NumberOfBillsWithError<br/><br/>
        ///// </summary>
        ///// <remarks>Mapped on: the scalar query expression for retrieving the # of bills-with-error for each batch</remarks>
        //public int NumberOfBillsWithError
        //{
        //    get
        //    {
        //        return (int)this[_parent.NumberOfBillsWithErrorColumn];
        //    }
        //}
        ///// <summary>Gets / sets the value of the TypedList field NumberOfBillsWithLineError<br/><br/>
        ///// </summary>
        ///// <remarks>Mapped on: the scalar query expression for retrieving the # of bills-with-line-error for each batch</remarks>
        //public int NumberOfBillsWithLineError
        //{
        //    get
        //    {
        //        return (int)this[_parent.NumberOfBillsWithLineErrorColumn];
        //    }
        //}
    }

}


Please note also that if the extended property of the typed is is all commented out then the problem goes away.

Please attach the code files rather then posting it inside the message body, I find it very hard to traverse your code.

Also I see many commented lines, would you please remove them out.

I think it's this:
Code:

fields.DefineField(new EntityField2("NumberOfBills",
                                                new ScalarQueryExpression(ClaimBillFields.Id.SetAggregateFunction(AggregateFunction.Count),
                                                                         (BatchFields.Id == ClaimBillFields.BatchId_))),
                             index++);

Please use the EntityField2() ctor overload which accepts a Type object and try again.

OK, I will clean up the source code and will attach it in soon.

Otis,
You were right on the money. It works. Could you please explain why llblgen v2.6 requires the datatype specified?

Thank you

BZ

In projections and other areas where the returnvalue of the scalar is needed, the type of the return value can't be determined in the .NET code, as it is unknown what value is returned from the scalar / aggregate / expression. So we needed the type to be specified as well. In previous versions this went wrong in some cases, hence the requirement.
