i got the same problem for many weeks ! http://jboss.org/index.html?module=bb&op=viewtopic&t=90035&po... take a look at jacote's message. i think this problem is not solved. http://jboss.org/index.html?module=bb&op=viewtopic&t=93276 "alexsmirnov" wrote : After lot of work, I was found source of problem. | For store per-applicaton instances of configurable JSF classes ( Factories etc ) JSF use context class loader ( Thread.currentThread().getContextClassLoader() ) as key in static Map ( as far as many web libraries ). | With installed portal service, Jboss call init() method of filter with different context, and incorrect classloader ! | As a result, JSF do not have acces to configured instances, and filter methods don't show application classes. | In lates release ajax4jsf, most of initialization work moved from init() method, and applications can work with Jboss portal service. | P.S. For properly work inside portal, we need more changes - this feature targetted to ajax4jsf 1.1 release. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4005387#...
