Subject Portlet Issue From Struts version 2.5 to 2.5.5?
Date Wed, 30 Nov 2016 22:30:29 GMT
We've been trying to upgrade from struts 2.5 to struts 2.5.5, and most of our
webapps are portlets. However, with struts 2.5.5 portlets throws the
following exception:

"java.lang.IllegalStateException: Not allowed in a portlet"

Below is the method in the classs
org.apache.struts2.portlet.servlet.PortletServletRequest where this always
happens:

	public Cookie[] getCookies() {
		if (portletRequest instanceof HttpServletRequest) {
			return ((HttpServletRequest) portletRequest).getCookies();
		}
		throw new IllegalStateException("Not allowed in a portlet");
	}

Apparently, the "portletRequest" variable is not an instance of
"HttpServletRequest".

That class is invoked by the class
org.apache.struts2.interceptor.I18nInterceptor, which I noticed was changed
from version 2.5 which used the old xwork package version of that class. I
also noticed that cookie handling was added in version 2.5.5.

Finally, below is a partial stack trace. Any help would be greatly
appreciated!

Thanks in advance!
