Spring Webflow Cannot call sendRedirect() after the response hasbeen committed

Question

I have and webapplication based in Spring Webflow and Primefaces, and sometimes when I execute the screen I get the IllegalStateException ... but is really weird since we are not making a call before render the screen to have this tipe of error... What else we need to look at to fix this error?

    SEVERE: Servlet.service() for servlet [Spring MVC Dispatcher Servlet] in context with path [/Project] threw exception [Request processing failed; nested exception is java.lang.IllegalStateException: Cannot call sendRedirect() after the response has been committed] with root cause

I keep running into this same issue as well. Usually (for me anyway) this is due to something being added to the flow that is not Serializable. You should get a more informative message by adding setting the log level to DEBUG for org.springframework.web.servlet.
