Subject Problem with interaction between i18nInterceptor and ExecuteAndWaitInterceptor
Date Tue, 02 Oct 2012 00:52:55 GMT
Hello,

I'm using the struts2 tiles plugin (v2.2.3) and I'm having a problem
using the I18nInterceptor with the ExecuteAndWaitInterceptor.
Essentially when I add the execAndWait interceptor (see xml below) for
some reason the localization no longer works and when I try to get
localized text (e.g. TextProviderSupport.hasKey) I get a
NullPointerException (see error) that I narrowed down to this code in
LocalizedTextUtil...

    358:public static String findText(Class aClass, String aTextName,
Locale locale, String defaultMessage, Object[] args) {
    359:    ValueStack valueStack = ActionContext.getContext().getValueStack();
    360:    return findText(aClass, aTextName, locale, defaultMessage,
args, valueStack);
    361:
    362:}

... I'm assuming my valuestack is null for some reason, but I cannot
figure out why. Any ideas?

Thanks,
Ryan
