Bug ID: 56888
Summary: [PATCH] XSSFDataValidation ignores "allow blank" read
from sheet, assumes true
Product: POI
Version: unspecified
Hardware: PC
OS: Linux
Status: NEW
Severity: normal
Priority: P2
Component: XSSF

Patch to not overwrite allow blank value
XSSFDataValidation.XSSFDataValidation(CellRangeAddressList, CTDataValidation)
calls ctDdataValidation.setAllowBlank(true), overwriting the original value
read from the sheet. That value is therefore unavailable.
Attached is a patch from a colleague, with tests, to call setAllowBlank(true)
in the DataValidationHelper instead, so it still defaults to true for write,
but allows reading the actual value from the sheet.
