IllegalStateException when redirecting from system event in JSF managed bean
----------------------------------------------------------------------------

                 Key: WELD-1037
                 URL: https://issues.jboss.org/browse/WELD-1037
             Project: Weld
          Issue Type: Bug
          Components: Web Tier integration (JSF, JSP, EL and Servlet) 
    Affects Versions: 1.1.2.Final
         Environment: JBoss AS7
            Reporter: Kristof Vanbecelaere


I have a view with a system event like so

<f:metadata>
   <f:event type="preRenderView" listener="#{fileUploadBean.checkAccessToken}" />
</f:metadata>

the listener is just a faces managed bean and performs a redirect using FacesContext.getCurrentInstance().getExternalContext().redirect(...);
This leads to an exception. When I disable Weld by removing the empty beans.xml file the redirect works fine.
