[Openinteract-dev] Help needed fixing a bug

[<ant...@he...>]

We have a problem that occasionally we get this kind of error messages 
in our log:

18:19:22 ERROR OI2.SESSION OpenInteract2::SessionManager (149) No value 
returned from _create_session; this shouldn't happen...

The mentioned _create_session is called at row 141 of 
OpenInteract2::SessionManager:

     my $new_session = $class->_create_session;

By looking at the implementations of _create_session in the subclasses 
of OpenInteract2::SessionManager, it seems to me that _create_session is 
no supposed to be called without parameters.

Now I would fix this but I'm not quite sure how ;)

It seems that this call happens when CTX->request->session contains a 
hashref which is not tied. I'm not sure how we can end up in this kind 
of a situation and I don't know a way to replicate the bug we are 
getting, so I don't know how (if at all) I could add the needed 
parameters to the _create_session-call.

Would somebody happen to have an idea of what might cause an untied 
hashref session and what would that hashref contain when this happens?
