possible bug in JRAbstractExporter ver.3.7.3

[ericlang80]

Hello everybody, i'm new in jasper, but  trying to fix my appication, i found a possible bug in JRAbstractExporter abstract class, in setPageRange() method.

Look at this condition:

    if (jasperPrint.getPages() != null)
        {
            lastPageIndex = jasperPrint.getPages().size() - 1;
        }

where getPages() never must be null, but is possible that be an empty list , where size is 0 and lastPageIndex becomes -1.

well, i hope that helps to jasper project.

Thanks, Eric.

Hello,

In fact, the operational fields are startPageIndex and endPageIndex. The lastPageIndex is used only for some strict comparisons in JRAbstractExporter, and -1 is one of its assumed values. There is no bug here.
