title: Getting warning from JSF: The response was already committed by the time we tried to set the outgoing cookie for the flash
body: <p>I have a page1.jsf, in this page i have a commandButton that put an object in ELFlash, and redirects to page2.jsf. In this page i recover the object by ELFlash. Everything works fine. But while the user remains in page2.jsf, for every ajax request, tomcat shows this warning message:</p>
