data store and proxy

[perrywu]

Experiencing very weird problem.
Trying sync a store with proxy that has api setting.
call store.sync() right after data loaded.
all my records just loads been recognized as 'new', so store basically call proxy api create and dump all data in the request string in json.
tried to verify by call store.getNewRecords() right after data loaded. All data just loaded returned with that call...
Is this a bug or I am using it wrong???

I got it...
Have to setup Model.idProperty.
Any model has no idProperty will be recognized at 'new' data.
