Should ROOT_QUERY be initilized by myself ?

[darkship]

Hi,
I came across an issue like this #1701.

It appears that when I start my app I don't have any ROOT_QUERY. So that whatever is in my query,store.readQuery({query}); throws "Can't find field on object (ROOT_QUERY) undefined."
Running store.writeQuery({query, data}}) creates ROOT_QUERY and the same readQuery call works afterwards.

Is this a bug or should I have used initStore ?

Hi @darkship If any of the data that readStore tries to read is not there, the function will throw an error. In your case there's nothing in the store at all, which is why it errors at ROOT_QUERY. You should protect the readStore call with a try/catch block if it's possible that the data might not be in the store yet.

OK, thanks

@helfer Why not just return null instead of throwing an Exception? I feel return null is more convenience.
