save ('ID',{docdata}, function does not work

[foxjazz]

I found that trying to use this function with the ID, it would always save with a generated id.
In order to get it to work on a new document, I had to add the _ID in the document with it populated.

I found problem like this.
My case is try to save Immediately after create DB.
Maybe its have a few time to create DB, then it has not done create DB when I tried save.

I think the solution is fix create() to need callback.
