Class SubFlowBackNavigationExceptionResolver

java.lang.Object
  com.ervacon.springframework.web.servlet.mvc.webflow.SubFlowBackNavigationExceptionResolver

All Implemented Interfaces:

org.springframework.context.ApplicationContextAware, org.springframework.web.servlet.HandlerExceptionResolver

public class SubFlowBackNavigationExceptionResolver

extends java.lang.Object

implements org.springframework.web.servlet.HandlerExceptionResolver, org.springframework.context.ApplicationContextAware

Exception resolver that tries to resolve navigation problems with sub flows resulting from the use of the browser Back button.

The strategy employed by this exception resolver is to retry the request after popping the top flow from the flow memento stack. This is not a 100% full proof technique, but it does help in a lot of cases.
