Class ScopeSearchingELResolver

java.lang.Object
  javax.el.ELResolver
      org.springframework.webflow.expression.el.ScopeSearchingELResolver

public class ScopeSearchingELResolver
extends javax.el.ELResolver

Custom EL resolver that searches the current request context for variables to resolve. The search algorithm looks in request scope first, then flash scope, then view scope, then flow scope, then conversation scope. Suitable for use along side other variable resolvers to support EL binding expressions like "#{bean.property}" where "bean" could be a property in any supported scope.
