Double results when updating grid dataSource?

[Kyle]

If you take a look at this fiddle:

http://jsfiddle.net/nYN8G/ 

You can see it sets the first fiddle to be user1. It then updates the datasource to be user2. However, it seems that it is just appending the secondary data source. Is this correct? How would I properly swap the data source?

Hello Kyle,

I suggest using the data method of the dataSource in order to rebind the grid. In case you want to read the original data again, you could call the read method.

I modified your sample to illustrate this approach, please check it here.
