Philippe Guinot commented on AS7-1485:
--------------------------------------

Hello,

I'm actually having troubles because of this JSF patch. Using jsf-impl-1.2_15-jbossorg-1, I can't load any of my facelet: I just get a 404 error !

If I replace in the JBoss module the JAR by jsf-impl-1.2_15.jar, then everything is fine.

I've put some breakpoints in the affected classes, but I can't see anything wrong: no exception is thrown. Here are the details about the class loaders:
* The previous TCCL: ModuleClassLoader for Module "deployment.My_EAR.ear.My_WAR.war:main" from Service Module Loader
* The new class loader ServletContextListener.class.getClassLoader() = ModuleClassLoader for Module "javax.servlet.api:main" from local module loader @ee51b2c 

If I comment the class loader settings, then it my facelets work again.

And I do not use Xerces other than the xercesImpl-2.9.1-jbossas-1 version in the org.apache.xerces module.

Thank you for your help.
