I have a dataview on a page with a microflow data source. It works fine. I have an action button (outside the data view) that calls a nanoflow which takes me to another page. When I click it, the dataview's data source executes AGAIN. Is this normal?
If you do a refresh of the object in your nanoflow then I would expect this behaviour.
Did you close the other page. Maybe you use the same object in the new page and the old page refreshes by loading the new one.
