I have a view with a system event like so

<f:metadata>
<f:event type="preRenderView" listener="#

" />
</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.
