Hello again,
I've found this interesting and seemingly useful piece of information in a struts book I recently obtained. Dynamic Forwards
ActionForward forward = new ActionForward("/do/itemEdit?action=edit");
Then it goes on to tell me to use the runtime parameter techniques in the previous sections to help build my ActionForward path. There are two techniques:
Adding parameters in the page or Adding parameters in the Action class:
ActionForward forward = mapping.findForward("article"); StringBuffer path = new StringBuffer(forward.getPath()); boolean isQuery = (path.indexOf("?")>=0); if (isQuery) path.append("&dispatch=view"); else path.append("?dispatch=view"0;
return new ActionForward(path.toString());
Ok, so having that found out... and with what you've given me from above can I do something like this?
::regular class stuff::
String previouspath = request.getSession(forward.getPath());
ActionForward forward = new ActionForward(previouspath);
::regular class end::
I'm going to try it out... if anyone sees me doing some really bad stuff feel free to slap my wrists :-P. Brandon
It won't work - you'd have to get the ActionForward of where you WERE, which is exactly why I recommended storing the forward in the session before you actually go there.
I was able to make this work!! You're absolutely right though. I realized that I set a bean in my page to handle my navigation so I checked for the value of that "page" and "step" and created the ActionForward based on that! If anyone wants to see I can post some code. Brandon
