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
> Configured but inexistent Renderer is not reported
> --------------------------------------------------
>
> Key: MYFACES-133
> URL: http://issues.apache.org/jira/browse/MYFACES-133
> Project: MyFaces
> Type: Bug
> Versions: 1.0.8 beta
> Environment: Tomcat 5.0.28
> Reporter: Alexander Jesse
> Priority: Minor
> Attachments: MinimalMyFaces.zip, MinimalRI.zip, TomcatConfig_Log.zip
>
> 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>
> )
