Local datastore strange behavior

[Oleg]

Hi All.

I trying to create a local data store like this (this is an official example from docs)

var movies = [ {

      title: "Star Wars: A New Hope",

      year: 1977

   }, {

     title: "Star Wars: The Empire Strikes Back",

     year: 1980

   }, {

     title: "Star Wars: Return of the Jedi",

     year: 1983

   }

];

var localDataSource = new kendo.data.DataSource({data: movies});

But i cannot get a data from the datasource:

localDataSource.data(); // returns "[]"

DataSource data size: 

localDataSource.total(); // returns "0"

Where I am wrong?
