Hi,

I was using VBCS with version 19.1.3 and now it has been upgraded to version 19.3.1.2. Some of the features like first-selected-row event is not firing for the first time. 

There is a master-detail table in a page. When user provides search parameters and clicks on search, the page displays data in the master table. A first-selected-row event is added on the table to call the service and populate the data in the detail table. But this event now is not firing when user clicks search for the first time. Subsequent search or if another row is clicked, this event fires. The selection-required property on the table is set to true. I was not facing this issue with the earlier version 19.1.3.
