RE: Problem with losing session context 'authentication' - lookin
g fo r workaround or bugfix
Hi Antonio,
I'll answer all questions here, and add the relevant code below (since it's
an enormous lot of code). The "getObject()" function is something I get from
my backend. It goes too far to explain it or to add the code (also a lot).
I'll add the relevant part of the sitemap and the javascript files, although
the login part is an almost exact copy of the "authentication with flow"
sample in Cocoon.
[1] = sitemap
[2] = login.js
[3] = pids.js (my "use cases")
[4] = authentication.xml (getuser)
Several problems occur at once:
1. when the authentication context in the session is lost, the
SessionTransformer throws an Exception. Since my error page includes a
"cinclude:include src='cocoon:/getUser'" I cannot properly display the
error.
2. If I go from one function to the next (e.g. from 'internal_addPerson' to
'prot_showDetails') I loose the session context (it references the internal
pipeline). If I go "public" (i.e. through the protect() function) it works.
Hope you have a clue. Thanks for bearing with me.
Bye, Helma

Change to:
<authentication uri="cocoon:raw://authenticate"/>
(I guess your authentication uri is in the root of your webapp).

Tip: Move the internal pipelines this first position. They will be jumped
by all the external requests and internal pipelines will be solved first
when they come in. If not the internal pipelines will be tested against
all the external pipelines matches.

Hi Helma!
I don't forgot to this task! As promised, I found the time and started to
checking the code :-D
I have the posted code in my computer. I just left the code that was
interesting to me:
[2] login.js
> cocoon.load("resource://org/apache/cocoon/webapps/authentication/flow/javasc
> ript/auth.js");
>
> function isLoggedIn() {
> var handler = cocoon.parameters["handler"];
> var resource = cocoon.parameters["resource"];
>
> // resource contains the URL where the request came from, so you can
> redirect to there
>
> if (auth_isAuthenticated(handler, resource)) { <---- neither
> redirection
> work
the auth_isAuthenticated() allow just 1 parameter. The correct code must be:
auth_isAuthenticated(handler).
See the source code:
http://cvs.apache.org/viewcvs.cgi/*checkout*/cocoon-2.1/src/blocks/authentication-fw/java/org/apache/cocoon/webapps/authentication/flow/javascript/auth.js?content-type=text%2Fplain&rev=1.9
Please try to change it and let me know if this solve the problem or not.
We can try to solve the problem fixing 1 thing at a time, OK? :)

Antonio Gallardo

The above file look quite old. The new implementation works. I am using
for months:
http://cvs.apache.org/viewcvs.cgi/*checkout*/cocoon-2.1/src/blocks/authentication-fw/samples/flow/sample.js?content-type=text%2Fplain&rev=1.5
