I am using WOLongResponsePage Component in my project.
But in the run time, it is showing the error message:
Session.context() evaluates to null. You may be trying to
get the context object
from an archived session object. there is no context
object outside of the
request-response loop.
The component is unable to generate response.
I would like to know how to access the Session context in
WOLongResponsePage performAction() method.
Please help in solving the above situation, if possible with
some code snippet.
Thanks and Regards,

You can't, and you shouldn't try.
A request is received and processed and a response is generated, and
this all happens in one thread, and it needs to be quick. While
this is happening you have access to the Session and the WOContext
in that thread.
What you need to do is get all the properties you need from the
Session or WOContext before you start the thread that does the long
response thing, and store them in instance variables in your
component, so that when the secondary thread is running it can use
those instead.
Also bear in mind that accessing the session's editing context within
the performAction thread is a sure path to deadlocks.
with regards,
