NullPointerException with empty sheetName #24

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago 
Found the bug. Stupid error.  Was setting this.sheetName correctly if sheetName 
param was null. But then used sheetName, not this.SheetName later on.  Renamed 
all parameters to be different than their global counterparts.

From post:

Using 1.2.9

If you use the constructor ExcelExport(table) you get a nullPointerException.

Caused by: java.lang.NullPointerException

It works if you specify a sheet name: ExcelExport(table,"my sheet")
