Subject RE: Problem with losing session context 'authentication' - lookin g fo r workaround or bugfix
Date Thu, 13 May 2004 11:55:13 GMT
Hi Joerg,

Yes, I have done some remote debugging, and I'm not sure if I've come across
the actual problem (my knowledge of the inner workings are too limited for
that). I did notice however that the
o.a.c.components.flow.javascript.fom.FOM_JavaScriptInterpreter$ThreadScope
has a variable "useSession" which is always "false". Its comment says:

        /* true if this scope has assigned any global vars */

As said, I'm not sure what it means, so I'm unable to figure out how to get
it to true and even if it's true whether it wil solve my problem. :-(

Bye, Helma
