Problem with Poi ForumulaRecord.getValue()

allelopath asked
Last Modified: 2012-05-12
We have a problem with ForumulaRecord.getValue() returning a 0 value when we know there should be a valid value. The problem appears to be somehow related to a "corruption" in the excel file. If we have the problem and then we save the file or open & repair the file, the problem does not occur (ie getValue() returns the expected value).

The formula is something like: =f4+g4+h4+i4

Any ideas about what is going wrong or what to do?

In our class that implements HSSFListener, we have:
	public void processRecord(Record record) {

		int row = 0;
		int column = 0;

		HSSFRow hssfRow = null;
		HSSFCell hssfCell = null;

		switch (record.getSid()) {
		case FormulaRecord.sid:

			FormulaRecord formulaRecord = (FormulaRecord) record;
			row = formulaRecord.getRow();
			column = formulaRecord.getColumn();
			// =f4+g4+h4+i4
			double doubleValue = formulaRecord.getValue(); // sometimes unexpectedly 0
