struts2 - UrlRewriteFilter skipping i18n Interceptor in Struts 2 -

i managed have struts 2 i18n interceptor working change session locale. it's working if call directly action, example:

https://localhost:8443/loadclientlogin.action?request_locale=fr

but if use urlrewritefilter map rule, calls action, seems 18n interceptor skipped, since locale not changed.

this url rewriter's rule wrote action:

<rule>     <from>^/client/login(\??)(.*)$</from>     <to type="forward">/loadclientlogin.action$1$2</to> </rule>

and url use change locale:

https://localhost:8443/client/login?request_locale=fr

by other side, if change type of rule "redirect" works, browser address show "ugly" forwarded url.

it's strange other custom interceptor use manage user session it's called always.

update:

i put log trace in action write locale session:

public string loadclientlogin() {     logger.debug("locale: " + actioncontext.getcontext().getlocale());     return action.success; }

when call directly action, log shows correct locale code:

locale: fr

but through url rewriter this:

locale: [ljava.lang.string;@4d227ffb

any suggestion appreciated.
