wave:selectionChanged is getting fired on page load.
I have a wave dashboard with a filter in it. I am using wave:selectionChanged to catch the filter selection value. The issue is wave:selectionChanged event is getting fired on page load itself. Because of which when a user clicks on "Update" button without selecting any value then my conditional error is not coming because there is no change in selection.
My concern is how can be sure that the event wave:selectionChanged is fired only when "Update" method is clicked and not on page load.
