[Seaside] hot to use response during action phase?

[Julian Fitzell]

How are you calling #response on WASession? it should be self
requestContext response addCookie:

Are you storing the request context somewhere? That would be the most
likely cause of the response being nil. You need to make sure to call
"self requestContext" at the point that you want to use to make sure
you are using the correct current context...
