WLP 10.3.2 ClassCastException in FacesContext

If you see:

java.lang.ClassCastException: com.bea.portlet.container.ActionRequestImpl

Try adding the following:

import javax.portlet.ActionRequest;

...
ActionRequest actionRequest = (ActionRequest) ctx.getExternalContext().getRequest();
HttpServletRequest httpRequest = (HttpServletRequest) actionRequest.getAttribute("javax.servlet.request");
