[Grok-dev] Multiple Model Issue

[Tim Cook]

Brandon & Leo,

Thanks for your replies.   

Leo - no I do not have any instances inside the application.  I haven't
gotten a View to work yet much less an addForm :-)

Brandon - your suggestion http://localhost:8080/b/bindex makes sense
because I am trying to create an in memory instance from the class
definition and that is what the context is set to.  However, I get the
same page not found error.    

The containers section of the tutorial seems as though I should get a
clue from it.  But, like most tutorials it is based on a pretty simple
example and I just can't make the connection to what I am trying to do.
This section of the tutorial has the user adding an instance directly
from the main application index.pt  

I will (eventually) need to render a page that creates in memory
instances of several classes so they can be added to the application in
the ZODB.  

Are there any examples like this?  

The best place to find more help on traversal as it seems to be where my
trouble is coming from?

Thanks,
Tim
