ToManyMapping saving instances twice

Esteban A. Maringolo
I'm importing a lot of objects from a plain text file, and for some reason I don't understand I'm getting the #items item of my parent object inserted twice.

I have the class Route that has many RouteItems.  

The importer code got somewhat convoluted, but basically what it does is:

glorpSession inUnitOfWorkDo: [:session |
       [ stream atEnd ] whileFalse: [
              route := Route new.
              session register: route
              route addItem: RouteItem new.
       ]      
].

If I run a simplified version of the above code, it works ok. So the mappings are fine.

Something like:

glorpSession inUnitOfWorkDo: [ :session |
| route |
route := Route new.
session register: route.
route addItem: RouteItem new.
session register: route.
route := Route new.
session register: route.
route  addItem: RouteItem new.
]


I can't understand what is causing the duplication of inserts in my "real" code.

Any clues?


Best regards,
