Setting floating point formatting locale for JSF / ICEfaces?

java jsf internationalization icefaces

I am writing a JSF (ICEfaces) application using resource bundles to handle internationalisation.

The application nicely applies the (default) Dutch "nl" locale for the resource bundle but fails to apply the same locale on formatting floating point numbers, even if I explicitly set the locale for a page using <f:view locale="nl">.

How do I make floating point numbers follow the current locale setting?

It is likely that you are not using a converter to format the numbers to the appropriate locale.

  <f:view locale="nl">
    <h:outputText value="#{numbers.someDouble}">
      <f:convertNumber pattern="#,##0.00;(#,##0.00)" />
    </h:outputText>
    <br />
    <h:outputText value="#{numbers.someDouble}">
      <f:convertNumber locale="en" pattern="#,##0.00;(#,##0.00)" />
    </h:outputText>
  </f:view>

This view (a Dutch locale view with a number, followed by an English locale number) produces the following output:

12.341.234,43
12,341,234.43
