Subject [jira] [Created] (TRINIDAD-2312) NullPointerException in CoreRenderKit.shortCircuitRenderView
Date Wed, 12 Sep 2012 19:56:09 GMT
Mike Calmus created TRINIDAD-2312:
-------------------------------------

             Summary: NullPointerException in CoreRenderKit.shortCircuitRenderView
                 Key: TRINIDAD-2312
                 URL: https://issues.apache.org/jira/browse/TRINIDAD-2312
             Project: MyFaces Trinidad
          Issue Type: Bug
          Components: Components
    Affects Versions: 1.2.14-core 
            Reporter: Mike Calmus


When FINE logging is enabled a NullPointerException can be thrown during PPR.

Caused by: java.lang.NullPointerException
	at org.apache.myfaces.trinidadinternal.renderkit.core.CoreRenderKit.shortCircuitRenderView(CoreRenderKit.java:371)
	at org.apache.myfaces.trinidadinternal.application.ViewHandlerImpl.renderView(ViewHandlerImpl.java:172)
	at org.springframework.faces.webflow.FlowViewHandler.renderView(FlowViewHandler.java:99)
	at org.apache.myfaces.lifecycle.RenderResponseExecutor.execute(RenderResponseExecutor.java:116)


The code in question is this:

          _LOG.fine("Page navigation to {0} happened during a PPR request " +
                    "on {1};  Apache Trinidad is forcing a redirect.",
                    new String[]{viewId, originalRoot.getViewId()});


Changing to:

          _LOG.fine("Page navigation to {0} happened during a PPR request " +
                    "on {1};  Apache Trinidad is forcing a redirect.",
                    new String[]{viewId, (originalRoot != null ? originalRoot.getViewId()
: null)});

should fix the problem.
