James: We are working in an integral components framework and one of the components is Struts navigation using a non intrusive stack:
We have an early access at http://opentranquera.sourceforge.net/ea/opentranquera-src-0.1-ea.zip You can take a look at net.sf.opentranquera.ui.struts.navigation package and the webapp/navigation web app, i know that we lack of documentation currently, but may it can be of your interest. I think this navigation scheme solves exactly your problem. You configure a webapp filter (in web.xml) that intercepts the calls and saves a stack. in this way you need not to code anything in your actions (nor extends any superclass) and all is solved in the filter. To go to the back page, you have to indicate an action in the struts-config and call it. Let me know if you have further questions. Saludos.
