--------------------------------------
Summary: NullPointerException in FlashImpl when forwarding from an
init action
Key: MYFACES-3673
URL: https://issues.apache.org/jira/browse/MYFACES-3673
Project: MyFaces Core
Issue Type: Bug
Components: JSR-314
Affects Versions: 2.0.16
Environment: Windows Myfaces 2.0.16, Jetty 8.1.3.v20120416
Reporter: Andreas Wuest
Hi,
the following exception occurs when ich try to forward from an init action the
preRenderView phase:
The xhtml page i call contains the following preRenderView listener:
<f:metadata>
<f:event type="preRenderView"
listener="#{localizedInitializerView.init}" />
</f:metadata>
In the init Method of the listener i am performing a forward to a different
page with the following
logic:
public void init() throws Exception {
// performs the forward
HttpServletResponse response =
(HttpServletResponse)
FacesContext.getCurrentInstance().getExternalContext().getResponse();
HttpServletRequest request =
(HttpServletRequest)
FacesContext.getCurrentInstance().getExternalContext().getRequest();
RequestDispatcher dispatcher =
request.getRequestDispatcher("localized.jsf");
dispatcher.forward(request, response);
//
FacesContext.getCurrentInstance().getExternalContext().redirect("localized.jsf");
FacesContext.getCurrentInstance().responseComplete();
}
The result is strange, because the forward just works fine, however i am always
getting the following
NullPointerException in the log file. Using a redirect instead of the forward
just works fine.
java.lang.NullPointerException
