Hi, suggested patch is here: https://issues.apache.org/jira/browse/MYFACES-3078
can you please review it and apply if is it proper? Regards, Kočičák > Hi > Add a param to disable JSP support looks like a good idea. With such > param we could solve this issue raised recently: > https://issues.apache.org/jira/browse/MYFACES-3104 MyFaces 2 with EL ? > 2.2 in Websphere 7 > regards, > Leonardo Uribe 2011/3/17 Martin Koci <martin.kocicak.k...@gmail.com> This approach cannot filter two resolvers: 1. org.apache.myfaces.el.unified.resolver.FacesCompositeELResolver 2. org.apache.myfaces.el.unified.resolver.ScopedAttributeResolver 1) the first one is instance of CompositeELResolver and serves as container for sorted/filtered list of others ELResolvers. Currently does something for JSP, so I suggest to introduce: o.a.m.SUPPORT_JSP = true|false content-param as mentioned in original mail thread "performance: disabling "old" technologies" and if this false, myfaces will not install FacesCompositeELResolver, but plain javax.el.CompositeELResolver as parent. 2) org.apache.myfaces.el.unified.resolver.ScopedAttributeResolver is the last one in chain and always calls setPropertyResolved(true); (JSF 2.1: 5.6.2.9 ScopedAttribute ELResolver) and pick up anything stored in the request, viewScope, session, or application scopes by name. In strictly CDI-based application with no direct modification of servlet scopes or view scope this resolver will never resolve a property. What to do with this one I don't know. Possibly we can use ELResolver transforming :) org.apache.commons.collections.Transformer and allow replace one resolver with another, for example: o.a.m.el.unified.resolver.ScopedAttributeResolver -> MyNotResovingResolverWhichCallsSetPropertyResolvedTrue el.ResourceBundleELResolver -> SpringMessageSourceResolver (we don't use ResourceBundle) el.BeanELResolver -> MemoryLeakFreeBeanELResolver Of course this functionality can be achieved by filtering out the unwanted resolver with predicate and adding own in faces-config (and sort it to proper position in chain) Regards, Kočičák Martin Koci píše v St 16. 03. 2011 v 11:29 +0100: > 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?
