Set decimal separator when using f:convertNumber

Question

I want to know how to set the default decimal separator on my JSF application. I have some that I need to format as money, with 2 decimals.

Answer 1

The default decimal separator depends on the locale used. You can set it in 2 ways:

1. On a per-view basis by the locale attribute of the <f:view> tag:

    <f:view locale="#{bean.locale}">
   

2. On a per-converter basis by the locale attribute of the <f:convertNumber> tag:

    <f:convertNumber locale="#{bean.locale}" />
   

It's unclear what locale you're targeting, but the use of . as fraction separator is typical for US dollars with a locale of en-US, for example. So you need to set it as such:

<f:convertNumber type="currency" currencySymbol="$" locale="en-US" />

It can also be obtained from a java.util.Locale bean property.

<f:convertNumber type="currency" currencySymbol="$" locale="#{bean.locale}" />

Note that I used type="currency", that's more self-documenting.
