ExtDirectStore returns wrong 'total' parameter#1

My POST query is looks like this: {"action":"users","method":"get_users_list","data":[{"start":0,"limit":3}],"type":"rpc","tid":5} and server respod: {"tid": 5, "result": {"records": [{"username": "admin", "id": 1}, {"username": "tester", "id": 2}, {"username": "user", "id": 3}], "total": 3}, "action": "users", "type": "rpc", "method": "get_users_list"} When I change Ext.PagingToolbar `pageSize: 1`, parameters become `"limit":1` and responded `"total":1`. I guess total is not get `paginator.count` but why? Method get_users_list exactly like README example @remoting(provider, action='users', len=1) def get_users_list(request): data = request.extdirect_post_data[0] users = ExtDirectStore(User) return users.query(**data)
