Connections not recognized by Design Studio

Hi,

I'm trying to reload a data source in order to refresh the data every time a button is clicked.  The data source is a BO universe, by first assigning it and then reloading, (see following code)  however, Design Studio does not recognize the Data Source cuid.

Nb - I have full administrator rights.

Can someone please tell me if this is possible?

If it’s not currently possible will reloadData() method for DSL connections be available in version 1.5?

SAP software details:  IDT Version: 4.1 Support Pack 2; Design Studio 14.0.5 (1.4); Real Time Functionality 14.2.0

Code: DS_1.assignDataSource("cuid:AfAIO0CZSjlAhfzS9.Kwu6Y", dataSourceType.QUERY, DS_1);

DS_1.reloadData();

Fig. 1 – cuid not recognized.

I’m able to get the cuid by hovering over the datasource, however, when I try to assign this it is not recognized.

Fig. 2 – Backend connection not valid.

Fig. 3 -  reloadData() method not available.

Any assistance would be much appreciated.

Thanks and regards,

Patrick.
