Cannot enter tax rate with decimal values (comma or dot); validation errors not localized #4014
Description
It is not possible to enter a tax rate with a decimal value in the new Dashboard.
When entering a value like 5.5, saving the entry triggers the validation error "Enter a valid value", even though this is a valid number.
When using the German locale format 5,5, the form shows the error **"Expected number, received nan"`.
Both error messages are not translated, although the user language is set to German.
To Reproduce
-
Set the Admin UI language to German.
-
Navigate to Settings → Tax Categories or any other place where a tax rate can be entered.
-
Create or edit a tax rate.
-
Enter a decimal number:
5.55,5
-
Attempt to save the tax rate.
-
Observe the validation errors.
Expected behavior
-
Decimal values should be accepted according to the current locale:
- English locale:
5.5 - German locale:
5,5
- English locale:
-
The Admin UI should correctly parse and store decimal tax rates.
-
Validation should not incorrectly fail.
-
Error messages should be localized based on the user’s selected language.
Actual behavior
- Input
5.5→ Error: "Enter a valid value" (not translated). - Input
5,5→ Error: "Expected number, received nan" (also not translated). - Saving the tax rate is not possible.
