             Summary: Portlet Issue with I18Interceptor
                 Key: WW-4722
                 URL: https://issues.apache.org/jira/browse/WW-4722
             Project: Struts 2
          Issue Type: Bug
          Components: Core Interceptors, Plugin - Portlet
    Affects Versions: 2.5.5
            Reporter: Todd Kofford


Portlets always throw the following exception:
{quote}
java.lang.IllegalStateException: Not allowed in a portlet
{quote}
Below is the method in the classs
*org.apache.struts2.portlet.servlet.PortletServletRequest* where this always
happens:
{code:java}
public Cookie[] getCookies() {
    if (portletRequest instanceof HttpServletRequest) {
        return ((HttpServletRequest) portletRequest).getCookies();
    }
    throw new IllegalStateException("Not allowed in a portlet");
}
{code}
Apparently, the "portletRequest" variable is not an instance of 
"HttpServletRequest".

*NOTE -* There are many other methods in class *PortletServletRequest* that use 
the exact same assumption/logic as the "getCookies()" method.

That class is invoked by the class
*org.apache.struts2.interceptor.I18nInterceptor*, which was just changed in 
version 2.5.5. See change [https://issues.apache.org/jira/browse/WW-4686]

Finally, below is a partial stack trace
