Class FlowPropertyResolver

java.lang.Object
  javax.faces.el.PropertyResolver
      org.springframework.webflow.executor.jsf.FlowPropertyResolver

public class FlowPropertyResolver
extends javax.faces.el.PropertyResolver

Custom property resolve that resolves active flow session scope properties from a thread bound flow execution.

TODO: this class probably needs to delegate to a strategy object pulled out of the appcontext, to provide ability to override and configure, as JSF provides no other way to customize and configure this instance.
