Extending model is not working when using associations. Problems reported here and here still present under B3.
Thanks for having a look at this, as it is a pretty serious limitation preventing use of the model package in real-world scenario.
The bug report you linked to: http://www.sencha.com/forum/showthre...ations-(4.0.1) is still marked as open.
