Problem with SHEET_NAMES parameter

[r3n4n]

 I set the parameter SHEET_NAMES:

exporter.setParameter(JExcelApiExporterParameter.SHEET_NAMES, new String[]{"Report0","Report1","Report2"});

And the parameter JASPER_PRINT_LIST with my printList with three JasperPrint elements:

exporter.setParameter(JExcelApiExporterParameter.JASPER_PRINT_LIST, printList);

But the three sheets, only the first is renamed according to the parameter SHEET_NAMES.
