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.
