Ok thank you SOLVED
Maybe bug in FortesReport
We have to modify :
rlfinddialog.pas
Add :
constructor CreateNew(AOwner: TComponent; Num: Integer=0); override;
constructor TfrmRLFindDialog.CreateNew(aOwner: TComponent; Num: Integer=0);
begin
inherited CreateNew(aOwner,Num);
Init;
end;
because we use createnew
thank you Attila
