Class OpenContextInViewInterceptor

java.lang.Object
  org.szegedi.spring.web.jsflow.OpenContextInViewInterceptor

All Implemented Interfaces:

org.springframework.web.servlet.HandlerInterceptor

public class OpenContextInViewInterceptor
extends java.lang.Object
implements org.springframework.web.servlet.HandlerInterceptor

A Spring handler interceptor that opens a Rhino context and associates it with the current thread for the complete duration of the handling, including view rendering. In most situations, you will not need a live Rhino Context object during view rendering, so you need not use this interceptor. However, if you receive an exception saying there is no current Rhino context during view rendering, you will need to use the interceptor.
