> It seems that EL Function which serialized to ViewState can't be resolved when the object is deserialize. Because the jboss-el directly use "Class#forName(String)". The code is as follows,
> {code:title=org.jboss.el.lang.FunctionMapperImpl.java|borderStyle=solid}
>         public Method getMethod() {
>             if (this.m == null) {
>                 try {
>                     Class t = Class.forName(this.owner);
>                     Class[] p = ReflectionUtil.toTypeArray(this.types);
>                     this.m = t.getMethod(this.name, p);
>                 } catch (Exception e) {
> {code}
> I think the above code cause ClassLoader Scope Problem. "Thread.currentThread().getContextClassLoader()" should be used.
> I found the jboss-el already had utility method for "Class.forName". It's "ReflectionUtil#forName(String)" method. Please use this method.
