📄 Description

🐛 Fix: Crash when editing amount filter with locale-formatted numbers

This PR fixes a bug where editing an amount filter causes a crash when using number formats that rely on commas or other locale-specific separators, such as:

  • 1.000,33 (German-style)
  • 1’000.33 (Swiss-style)
  • 1 000,33 (French-style with space)

❗ Bug Behavior

  • Users can create an amount filter like “is less than 1.000,33” — which works fine.
  • However, when they edit the filter (e.g., change “is less than” to “is greater than”), the app crashes with:
Error: safeNumber: number is not an integer: null
at safeNumber (util.ts:307:15)
at integerToCurrency (util.ts:319:20)
at FilterExpression.tsx:166:78

This is because the internal number parsing fails for some localized number strings, leading to null being passed into safeNumber().

🔍 Root Cause

The previous implementation didn't fully handle:

  • Grouping separators: ., ', space
  • Decimal separators: ,, .
  • Variants like 1 000,33, 1’000.33, etc.

These would parse incorrectly or return NaN, eventually leading to a crash when safeNumber(null) is called.

✅ Solution

The fix includes:

1. Locale-Aware Parsing Layer

  • Introduced parseCurrencyString (strict + loose modes).
  • Used by currencyToAmount() and parseAmountFromEditorInput().

2. Editor Value Handling

  • In FilterExpression.tsx, changed how filter inputs are parsed and displayed:
    • Use formatAmountForEditor() to format numbers properly for input.
    • On save, parse user input back using parseAmountFromEditorInput() and pass it as an integer.

3. Safe Fallbacks

  • If parsing fails, null or 0 is returned (depending on usage), and crashes are avoided.

🧪 Tests

  • All existing tests pass except two:
expect(currencyToAmount('3.45060')).toBe(3.4506);
expect(currencyToAmount('3.456')).toBe(3.456);

  • These fail because the new parsing enforces a strict 2-decimal precision (which aligns with typical currency formatting).

  • Let me know if that precision should be relaxed or adjusted in a follow-up.

🧩 Notes

  • This fix supports localized formats like:

    • 1.000,33
    • 1’000.33
    • 1 000,33
    • 1,000.33

  • Gracefully handles invalid input without crashing.

  • Handles both strict parsing (for controlled logic) and loose parsing (for flexible user input).
