Hi, 

Im trying to set a remote datasource's data to an array initially, and then execute the read() method later to retrieve its remote data. But for some reason the read() is not executing the remote call, and the subsequent datasource.data() is just returning the initial array.

Dojo Code: http://dojo.telerik.com/INUWe

Please advise.

Kind Regards,
Grant

Hello Grant,

The second time the data method is still returning the array data because it is executed exactly after the read and the new data is still not fetched from the server.

If the second data() method call and console.log are in setTimeout around 1000ms, the new data will be fetched and shown correctly:

Thanks Stefan, 

This make perfect sense, it slipped my mind that the read() returns a promise that must be resolved, instead of an instant response.

Thanks again,
Grant
