Subject RE: Does Struts automatically populate an actionForm in session scope??
Date Tue, 25 Mar 2003 16:22:13 GMT
Click, I think the light bulb just went on.So, in general the sequence
is something like this???????

1. A user requests a form
2. Struts creates a session actionForm (based on scope setting in action
3. ??? Does the first jsp need <jsp:usebean scope="session" name="x" />
or does Struts know that the bean is in session scope? Does Struts put
the sessionid inside the form?
4. User submits form for first time and Struts populates the actionForm
5. action gets form, if access to form data is needed use
request.getSession() and modify as needed.
6. return mapping.findforward("sucess")
7. The next page has to have <jsp:usebean scope="session" name="x" />
8. The user adds/modifies data and submits form.
9. Struts does NOT populate actionForm
10. action has to HttpSession session = request.getSession();
session.getAttibute(attributename) or session.setAttribute(attibutename)
11 repeat 7-10 as needed.
