Context state on redirect

Lewismcm

Hi All,

I have a rather strange problem with the forward action on a pre controller.

I have a pre controller which makes changes to the context session, which changes the logged in state depending on various variables, then redirects to another page.

However the changes made to the context are not being stored. So I am getting stuck in an infinite loop.

Has anyone else came across this problem?

I have tried passing the context via Url redirect and tried the context redirect.

Hi Sahu,

Yes I am debugging the session.getLoggedIn() and on page load it says the user is not logged in. After changing that to true I print it out again and it says the session is now logged in.

After that I perform a redirect however the session state is again logged out...

How are you modifying the session information? It will not be possible to go into details without seeing the actual code.

even something simple like setting an attribute gets lost. the value is NEVER set when you first enter the controller, but the final debug statmeent proves the set is working. so the forward action seems to lose this change.


String saveAttrib = (String)context.getSession().getAttribute("TEST");
LOGGER.debug("Saved value: " + saveAttrib);
context.getSession().setAttribute("TEST", "valueexists");
saveAttrib = (String)context.getSession().getAttribute("TEST");
LOGGER.debug("Saved value (after): " + saveAttrib);

Can you guys check the actual session information by using getHttpSession() method in the code to see if its the same session which tries to access information both the times (when it returns value in debug statement and when it doesnt on forward request). It doesnt look right that same session is returning different information at different times.

Not sure which method i should be testing. I did the following:


LOGGER.debug("context.getRequest().getRequestedSessionId() : " + context.getRequest().getRequestedSessionId());
LOGGER.debug("context.getRequest().getSession().getId() : " + context.getRequest().getSession().getId());

getRequestedSessionId() always returns a different value. getSession().getId() alwasy returns the same value. Any thoughts? Which is the correct one for identifying my current session?

It seems when i go to another page first then to the login page, there is a valid session (via getRequestedSessionId()), and everything works ok. But when i try to go straight to a secured page, the framework redirects to the login page. But the precontroller on this page has no valid session. so nothing i set on the session is saved. and then the redirect sends back to login in a loop because a new session is never created.

You are checking this out on Run time Enviornment or Authoring Env.? Are you using OOTB Login component for this functionality or a custom one?

PaulW

runtime environment.

i have my own LoginController. But this doesnt seem to be a login issue. Its more a controller issue. if i drop any controller onto a page as a precontroller, the code cant set session parameters if the page is the first one accessed.

Can you do one thing: Instead of forwarding request to login page, can you forward to a simple HTML page and access the session variable in that HTML page which you have set in first page. This will ensure that the problem is not with your LoginController.
