Caused by: java.lang.IllegalArgumentException: sheetName must not be null

[GoogleCodeExporter]

What steps will reproduce the problem?
1. excelExport = new ExcelExport(mainTable);
2. excelExport.export();

What is the expected output? What do you see instead?

NOW:
public ExcelExport(final Table table, final Workbook wkbk, final String 
sheetName, final String reportTitle, final String exportFileName, final boolean 
hasTotalsRow)
... 
        sheet = workbook.createSheet(sheetName);
...
MUST BE:
public ExcelExport(final Table table, final Workbook wkbk, final String 
sheetName, final String reportTitle, final String exportFileName, final boolean 
hasTotalsRow)
... 
        sheet = workbook.createSheet(this.sheetName);
...

What version of the product are you using? On what operating system?

1.2.9
