Allow NumberConverter to recognize both breaking and non-breaking spaces as
grouping separators in the French locale
--------------------------------------------------------------------------------------------------------------------
Key: MYFACES-1743
URL: https://issues.apache.org/jira/browse/MYFACES-1743
Project: MyFaces Core
Issue Type: Improvement
Components: General
Affects Versions: 1.1.5
Environment: Client: IE 7 and Firefox 2.0 on Windows XP Pro
Server: Windows Server 2003, Java 1.6, Tomcat 5.5, JSF 1.1.5
Reporter: Mathieu Vézeau
In the French locale (fr) and possibly others, the grouping separator used by
DecimalFormat is the non-breaking space character (unicode '\u00A0'). However,
when a user enters a space in an HTML text field, both IE and Firefox on
Windows send a normal space (unicode '\u0020'). As a result, the grouping
separator is not recognized and the number is truncated: 10 000 becomes 10
after parsing.
While JSF is technically correct here (it just delegates to DecimalFormat), it
would be nice if NumberConverter was modified to also accept normal spaces as
grouping separators. One way to do this would be to simply replace all normal
spaces by non-breaking ones in the input string, no matter what the locale. The
only downside that I see is that this could be considered a 'hack', i.e. not a
very elegant solution.
