grid editing new row - set default value in picklist

http://www.smartclient.com/smartgwt/showcase/#grid_editing_new_row

Hello Isomorphic,

The above is the example for adding new rows in grid list. The problem that I am having is setting a default value for "Continent" in the above example i.e., When "edit new" button is clicked the "Continent" picklist must display "North America.



Appreciate you help very much

Thanks much in advance
