Probably the biggest issue with this is that it assumes the existence of pushPayload, which only exists on RESTAdapter.
That said, I think I could live with this, if it was called pushPayload. I need to talk to Tom about it. In the meantime, can you rename it?
Add pushPayload method to store
@wycats done, that is obviously a better name and I don't know why I didn't use it in the first place.
I'm going to merge this, but I would like it if you opened a new PR with additional documentation that explained the expected payload format for the REST Serializer.
Do you mean in the YUI doc above the method?
