i have a strange problem and can't find anything about...
i have a grid (models+store+...) that is loaded from my backend via REST.
the backend sends a list of objects (some with id - these records exist in the database, and some without id - these records are phantom records).
with ExtJS 4.0.7 this worked perfect, the records with id became the right id and the records without id where added as phantom records to the grid.
since the update to 4.1 RC2/RC3 the records without id get the id 0 and are not phantoms
this is really a problem, cause the user should save (create) the phantom records to the database by click on them. but Ext thinks they already exist in the database and tries to update them (REST) and this fails in the database.
So what changed with the model/id/phantom stuff?
