Subject [Bug 57475] New: The Match function does not perform implicit conversion
Date Wed, 21 Jan 2015 14:37:48 GMT

            Bug ID: 57475
           Summary: The Match function does not perform implicit
           Product: POI
           Version: 3.9-FINAL
          Hardware: All
                OS: All
            Status: NEW
          Severity: normal
          Priority: P2
         Component: SS Common
          Assignee: dev@poi.apache.org
          Reporter: cquezel@gmail.com

If I call MATCH (EQUIV) with a SearchCriterion whose type is different from the
type of the elements of the LookupArray, the function returns N/A even if the
types are convertable.

if SearchCriterion is of type string whose value is convertable to a number
('1' for example) and LookupArray contains elements whose type is Number
({1,2,3} for example) then Match returns N/A while Excel and LibreOffice find a

public final class Match extends Var2or3ArgFunction {
private static int findIndexOfValue(ValueEval lookupValue, ValueVector
            boolean matchExact, boolean findLargestLessThanOrEqual) throws
EvaluationException {

    // Next line return false when classes dont match
    if(lookupComparer.compareTo(lookupRange.getItem(i)).isEqual()) {

Because ...

        public final CompareResult compareTo(ValueEval other) {
            // Next line does not convert
            if (_targetClass != other.getClass()) {
                return CompareResult.TYPE_MISMATCH;
            return compareSameType(other);
