Subject Re: [jira] Commented: (MYFACES-133) Configured but inexistent Ren derer is not reported

But this is something different what you are doing - you are having a
component which has a renderer-type set, and an appropriate renderer
for this component can not be found.

The bug was about changing a renderer-class to an uninstantiable class.

regards,

Martin

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.
