Rails - Feb 2007 - "ObjectName can't be referred" error - session serialization

All,

I''m getting the following error:

TypeError (TargetList can''t be referred):
   
C:/ruby/lib/ruby/gems/1.8/gems/actionpack-1.12.5/lib/action_controller/session/active_record_store.rb:81:in
`dump''
 
C:/ruby/lib/ruby/gems/1.8/gems/actionpack-1.12.5/lib/action_controller/session/active_record_store.rb:81:in
`marshal''
   
C:/ruby/lib/ruby/gems/1.8/gems/actionpack-1.12.5/lib/action_controller/session/active_record_store.rb:133:in
`marshal_data!''

It appears to be occurring when I''m attempting to render something, and
the session is being serialized.  Anyone seen an error like this?

I can''t figure out what it''s supposed to mean.

Thanks,
Wes

OK, I don''t know exactly what this was, but I was attempting to store a
collection of AR association objects in an object that was in the 
session.

So, imagine Parent has_many Children and @parent is an instance of 
Parent.

I was setting one of my object''s attributes to @a.children and putting 
it into the session.  Each of those objects in the collection is 
actually an A object somehow - which again, seems to have to do with the 
association magic.

Anyhow, I just took that out of the session (where it didn''t belong 
anyway, since the whole point of what I''m doing is to use a custom 
caching scheme to persist across requests), and everything''s fine.

I''m not sure what broke, but I will be wary about putting objects in
the
session which contain sets of associations stored in any of their 
attributes.

Thanks,
Wes

It''s weird though.  I''m able to set an attribute on my object
to the
equivalent of Parent and throw it on the session and it''s fine.

Argh.

I did not find out what this was.  Sadly, I''m having trouble
deciphering
what I meant when I wrote this as well :(...
