BigDecimalField handle currency formatted text replacement

[jptinsman]

Issue: When tabbing through a form and into a BigDecimalField, the user would normally just type in the desired number for the field. If the BigDecimalField has a currency format (i.e. $100.00), when the user types in a number (i.e. 150), it fails format validation and does not take the new number.

Solution: I have updated the BigDecimalField to check if the input matches the format. If it does, then it will use the format. If the input does not, then it attempts to directly input the number as a BigDecimal. If that throws an InvalidArgumentException, then it will revert back to the previous value (as with current logic).

Added two unit tests to validate the up/down with currency format as well as text replacement.

(Also included with this is adding a CSS styled BigDecimalField to the sample)

Hi Jonathan,

thanks, I’ll have a look into that and will come back to you.

Cheers

Hi Jonathan,

I see your point, but the problem is, that those signs (currency or
percentage sign in a percent field) are part of the format and might have a
functional role in the parsing. In the case of currency your example works
and parses correctly but in the case of percentage the parsing is not
correct anymore after your change (see the demo). I would like to stick to
the old version for two reasons:

• Any chosen NumberFormat should keep its excepted functionality when it
  comes to parsing (with the drawback that a user has to enter e.g. a
  currency sign if the format requires to)
• The BigDecimalField tries to mimic the JFormattedTextField in swing and
  that behaves like the current implementation of the BigDecimalField

As a consequence/workaround I personally do not use units within the fields
in my UIs and move them to the according field label as I agree that it is
annoying to type the unit each time you change the value.

Does that make sense?

Thomas
