jakarta.el.ELResolver

org.springframework.webflow.expression.el.ScopeSearchingELResolver

public class ScopeSearchingELResolver
extends jakarta.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.
