Subject [jira] [Commented] (WW-4677) I18N Interceptor Automatically validates locales
Date Thu, 18 Aug 2016 07:06:21 GMT

    [ https://issues.apache.org/jira/browse/WW-4677?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15426004#comment-15426004

Lukasz Lenart commented on WW-4677:
-----------------------------------

We can do both things, strict validation against {{getAvailableLocales()}}, a regex validation
and no validation. It can be global setting (via Struts constant) or per interceptor stack
(which is more flexible)

>             Project: Struts 2
>          Issue Type: Improvement
>          Components: Core Interceptors
>    Affects Versions: 2.5
>         Environment: 2.5.1 running on Java 8, RHEL Linux 6/7 
>            Reporter: Zoran Avtarovski
>             Fix For: 2.5.3

> There is an annoying issue with the I18N Interceptor, which now validates locales against
the list of default available locales in this bit of code:
> {code:java}
> if (locale != null && Arrays.asList(Locale.getAvailableLocales()).contains(locale))
{
>     locale = Locale.getDefault();
> }
> {code}
> The problem is I have a web app for refugees and not all the languages are in the available
locales array. This must be relatively new as it worked in the old version 2.x ish.
> Ideally it would be great if we could add a parameter (or constant) to bi-pass the validation.
> For example a tag in the struts.xml file:
> {code:xml}
> <interceptor-ref name="I18nInterceptor">
>   <param name="validation">
>      false
>   </param>
> </interceptor-ref>
> {code}
> and then access it in the interceptor to override default behaviour.
