Bug ID: 64459
Summary: Wrong IF behavior in array formulas
Product: POI
Version: unspecified
Hardware: PC
OS: Linux
Status: NEW
Severity: minor
Priority: P2
Component: SS Common
Assignee: dev@poi.apache.org
Reporter: r3m...@gmail.com
Target Milestone: ---
I have a simple formula: 'IF(FALSE(),#VALUE!,1)'
Naturally, this formula should always return 1, but when I put it as array
formula, it returns '#VALUE!'.
This is due to this part:
https://github.com/apache/poi/blob/REL_4_1_2/src/java/org/apache/poi/ss/formula/functions/IfFunc.java#L185
This piece of code is invoked only in array context and it specifies that if
second argument (value returned if condition is true) is of type ErrorEval, it
is returned regardless of the condition result.
I believe this is wrong and error should be returned only if condition
evaluates to true - but this is based only on this simple example. Are there
some other use cases that make this piece of code actually viable?
