You can use the Community commons library function from the appstore, which contains the refreshClass method which will refresh the entity displayed in the Listview =>
And then combine this with the Microflow timer widget, which will update your entity data with in certain time=> https://appstore.home.mendix.com/link/app/27/
Hope this will be useful.
If the only change in the database you do is adding the new record, you can simply refresh the record in the client when you commit it and it'll appear directly in the list view.
With kind regards,
Would't it work with an scheduled event that trigger a data source MF of the list view?
