Hi,
after few months I have time to do some performance optimalization for myfaces. This one is related to topic http://www.mail-archive.com/dev@myfaces.apache.org/msg49177.html Problem: how to disable ELResolver smartly? Adding a context-param for each is an overkill. But we have https://cwiki.apache.org/MYFACES/elresolver-ordering.html in codebase already. I propose to add new feature "ELResolver filtering" and new context-param: <context-param> <param-name>org.apache.myfaces.EL_RESOLVER_PREDICATE</param-name> <param-value>org.foo.bazz.ELResolverPredicate</param-value> </context-param> Filter is simple instance of org.apache.commons.collections.Predicate. For application where no ManagedBean(Resolver) is used or no Flash, user can simply return false from Predicate.evaluate and ELResolver won't be installed. WDYT? Regards, Kočičák
