Martin Marinschek commented on MYFACES-133:
-------------------------------------------


This is the corresponding source-code:

                javax.faces.render.Renderer renderer = null;
                try {
                  renderer = (javax.faces.render.Renderer) ClassUtils.newInstance(element.getRendererClass());
                } catch(FacesException e) {
                  // ignore the failure so that the render kit is configured
                  log.error("failed to configure class " + element.getRendererClass(), e);
                  continue;
                }

I would suppose that the logging should be exactly what you refer to, I don't know why this would still not be logged?

regards,

Martin

>      Project: MyFaces
>         Type: Bug
>     Versions: 1.0.8 beta

> A configured but inexistent renderer is not reported and the myfaces-application starts using the supplied standard renderer. The SUN-RI reports a "java.lang.ClassNotFoundException: com.jsf.components.renderer.NotExistingRenderer" which helps to pinpoint the configuration error.
> For production this can be a desired behaviour but presents some danger at the same time. Not having the information at hand I wondered why my renderer would not decorate the input-field as planned. When I tried the same renderer in the RI the error (wrong classname) was found in 30 seconds.
> The error is easy to reproduce:
> Take an existing JSF-application and add a phantom renderer to the faces-config.xml. Then start the web-container.
> (sample config-entry:
> <render-kit>
>  <renderer>
>   <component-family>javax.faces.Input</component-family>
>   <renderer-type>javax.faces.Text</renderer-type>
>   <renderer-class>com.jsf.components.renderer.NotExistingRenderer</renderer-class>
>  </renderer>
> </render-kit>
> )
