- Line 31: Update the column value getter in generateCalculationRows to
normalize missing or undefined values by returning null, while preserving
existing non-null values. Ensure the getter satisfies its CustomAggridValue |
null contract.

And why undefined here btw ?
There was a problem hiding this comment.
This undefined is crucial to keep existing formulas having this type of syntax "typeOf(IT10_Or) == 'undefined' ? IT10_Ex : typeOf(IT10_Ex) == 'undefined' ? IT10_Or : max(IT10_Or, IT10_Ex)" which are largely used in production.
As of today empty values were treated as undefined. In order to keep the system working while treating empty value as null, we now do the inverse and inject undefined in the scope when the value is empty
But if it's equal to 0 it should stay 0 you're right
Edit: same as above for the nullish coalescing operator

Okay thanks, maybe update the comment to make it more explicit ?

To keep ISO behaviour, I think you need to change this also |

- Line 40: Update the boolean formula-value flow around limitedEvaluate so null
is normalized to undefined, or ensure BooleanCellRenderer treats null as absent,
preserving the empty-value behavior used by DefaultCellRenderer and
NumericCellRenderer.
