TRVItemList object range is 0..0

[Ceprotec]

My reports are generated in a hidden form (the Show method is never called).

Most reports work well. However, some have exceptions when calling the Format method.

CallStack:

Code: Select all

System.Classes                          TList.Get
CRVData                      11601   +1 TCustomRVData.GetItem

UReportGeneratorForm        3083  +27 TReportGeneratorForm.ActionGenerateReportExecute

Code: Select all

GenerateReport ( srveResult , RVReportGenerator1 ) ;
srveResult.Format; // exception here

Code: Select all

exception number   : 1
exception class    : EListError
exception message  : List index out of bounds (1). TRVItemList object range is 0..0.

Any tips?

I will send the report template to your email.
