Setting floating point formatting locale for JSF / 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 loc开发者_如何学Pythonale 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


You can use nest <convertNumber> tag and set the default locale to "nl" in faces.config.xml. That way, the converters automatically get and use the default locale and you do not need to specify a pattern at each <convertNumber> tag.

faces-config.xml:

    <application>
        <locale-config>
          <default-locale>nl</default-locale>
        </locale-config>
    </application>
