Matthias Weßendorf commented on MYFACES-1782:
---------------------------------------------
In the original version of NumberConverter a currency string (for some Locale's
like fr_FR or fi_FI) can't be convertered, when value submitted via web-browser
(like "12 345,68 €").
The Java API of NumberFormat is expecting a nb space inside the "numbers" as
the grouping separator.
A String like "12\u00a0345,68 €" would be OK.
The fix is to replace the grouping_separator, when the grouping_separator is a
nb-space ('\u00a0'), with a regular blank (" ").
So a String like "12 345,68 €" would be OK as well.
Now... a String like ("12\u00a0345,68 €") would fail (which is only the case if
not edited etc).
In case the format.parse() is really failing... we re-replace the
grouping_separator and call format.parse() again.
The patch also contains two tests, which proof the behavior.
Attaching as a patch, to check with the TCK.

>
> This test-case shows, that there is a failure inside the standard
> NumberConverter (MyFaces):
> protected void setUp() throws Exception
> {
> super.setUp();
> mock = new NumberConverter();
> mock.setLocale(Locale.FRANCE);
> FacesContext.getCurrentInstance().getViewRoot().setLocale(Locale.GERMANY);
> }
> public void testFranceLocale()
> {
> UIInput input = new UIInput();
> mock.setType("currency");
> Number number = (Number)
> mock.getAsObject(FacesContext.getCurrentInstance(), input, "12 345,68
> €");
> assertNotNull(number);
> }
> the grouping_sep should be a nb-space...
