"Invalid floating point operation" when ShowReport
DeYo
Pozarevac, Serbia
I'm using Fast Report 2.5.3 and Delphi 7.
My problem: I have made Report (type Single). When I call Report from my program with frReport1.ShowReport for the first time it shows, but when I return to program and then try again I get the error message "Invalid floating point operation". Well, I need to have this work correctly becuse I need to enable more than one printnig in my program.
I have tried next
then I have tried not to use Show methods, so I have inserted frPreview component and connected it with frRaport.
same error.
then I have tried dinamically
only thing that worked (partially) was when I have set frReport's property StoreInDFM to true, to avoid extra loading (!?). Only line of code was: frReport1.ShowReport. Well, now Report was showed first time and second time, but on third attempt - same error.
Error was appearing no matter what was stored in frReport (DetailBands, OLE Objects, RichEdit...).
Any ideas???

Form2:=TForm2.Create(Application)

Comments
What happens is that (for some reason) FastReport sometimes when saving Report sets first page's property Size to -1 (by default it's "A4 210 x 297 mm"). I don't why this happens but when I change the property back to default it all worked correctly.
