Bug ID: 59199
Summary: setting null value to date cell leads to NPE
Product: POI
Version: 3.14-FINAL
Hardware: PC
Status: NEW
Severity: normal
Priority: P2
Component: XSSF
Assignee: dev@poi.apache.org
Reporter: jupp.str...@gmx.de
When setting a Date value in a cell and the date is null, a
NullPointerException is thrown.
Example:
private void createRow(Sheet sheet, Person person) {
Row row = sheet.createRow(0);
Cell cell = row.createCell(0);
cell.setCellValue(person.getBirthdate());
...
If person.getBirthdate() is null we get a NPE:
java.lang.NullPointerException
at java.util.Calendar.setTime(Calendar.java:1770)
at org.apache.poi.ss.usermodel.DateUtil.getExcelDate(DateUtil.java:76)
at org.apache.poi.xssf.usermodel.XSSFCell.setCellValue(XSSFCell.java:742)
My workaround is to check for null and in this case set
cell.setCellValue((String) null);
However, in my opinion Cell.setCellValue(Date value) should take care of this,
just like Cell.setCellValue(String value)
