    [ https://issues.jboss.org/browse/RF-10787?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12589465#comment-12589465 ] 

Martin Kočí commented on RF-10787:
----------------------------------

Here is example why order of resolvers is important, for example for RENDER_RESPONSE phase:

ELResolver: class org.richfaces.skin.SkinPropertiesELResolver
getValue invocations: 64306 getValue hits: 0
getType invocations: 0 getType hits: 0
invoke invocations: 0 invoke hits: 0
isReadOnly invocations: 0 isReadOnly hits: 0
setValue invocations: 0 setValue hits: 0

ELResolver: class org.richfaces.resource.ResourceParameterELResolver
getValue invocations: 64306 getValue hits: 0
getType invocations: 0 getType hits: 0
invoke invocations: 0 invoke hits: 0
isReadOnly invocations: 0 isReadOnly hits: 0
setValue invocations: 0 setValue hits: 0

...

ELResolver: class javax.el.BeanELResolver
getValue invocations: 62192 getValue hits: 40563
getType invocations: 0 getType hits: 0
invoke invocations: 0 invoke hits: 0
isReadOnly invocations: 0 isReadOnly hits: 0
setValue invocations: 0 setValue hits: 0
