AccessViolation in function TppCustomReport.GetGroupCount: Integer using RB18

rbuser

Hi,

after upgrading from RB17.02 to 18.00 nearly all reports create an
AccessViolation in

function TppCustomReport.GetGroupCount: Integer;
begin
Result := FGroups.Count;
end;

as FGroups is nil.

Recompiling our software using 17.02 everything works fine.

Any ideas

Tia Carsten

where aReport originates from

if lbConvert then

Convert(FVersionNo);
//Patch CE
TReportConverter.convert(TppReport(self),FVersionNo);
//EOP
FConverted := True;
end;
out of TppProdducer.loaded

Hi Carsten,

This is not a known issue.

My suggestion is to trace into your TReportConverter class and see
exactly what is happening.

Also, starting with RB 18, we added the TppTemplate.OnConvert event
which fires when loading a report saved with a prior version. This
would be a better place to perform your custom conversions rather than
the Loaded event of the producer.

Hi Nico,

Problem was found, caused by a hardcast.
Solution was using a softcast.

Thank you for the hint with TppTemplate.OnConvert, I will test it.

Thx
Carsten
