"receiver of session is nil"

Hi list,

When a session has expired and I try to access my app, I get a "receiver of session is nil" error (I just ignore it and re-try to access the app, then it works).

Is there something I'm doing wrong? How should one handle session expiration?

Thanks!

Re: "receiver of session is nil"

Hi,

Which version number of Iliad is it ?

I tried it on 0.9.1.1, and it works.

Best regards,

Some code at where the error occurs might be helpful for us.

By the way, the documentation's "Managing sessions" section is very helpful. Here is how to handle session expirations:

My version is 0.9.1-SA.

I've just tried to inspect a currently active session, run self expire then access the website.

Here's the whole stack dump: http://pastie.org/1707998

Maybe I should add I'm running in debugMode, in deploymentMode (of course) I don't get any error, but I still got to refresh the page to access it.

Thanks Nico, I managed to understand it and fix it. I was not implementing onExpire the right way :)

IIRC it works this way so the expiring session has a chance to handle
the request and you can trigger some action and display infos to the
user.

See ILApplicationHandler>>handleRequest and ILSession>>onExpire

Cheers,
Nico
