How to refresh Design Studio dashboard with (DSL - Universe Connection)

Hi All,

I have developed a dashboard with Design Studio 1.5 based on Universe (DSL connection).

My universe's backend is SQL Server.

Requirement - To refresh/reload the entire dashboard based on Dropdown (Select REGION) by user.

I have referred to the below thread by Mustafa Bensan which explains the below function as an alternative to DS_1.reloadData();

DS_1.assignDataSource( dataSourceConnection, dataSourceType, dataSourceName);

But, I am not able to see the universe connection/name listed to update - 'dataSourceConnection'

Refererence - http://scn.sap.com/message/15747912#15747912

Could you let me know what are the values I should fill for 'dataSourceConnection' and 'dataSourceType'

Is it not possible to refresh dashboard with DSL connection at all?

Many thanks,
