I tried placing DataView on both Layout and Page to display entity data. However, the DataView on Layout did not render data. When I reloaded the browser, both DataViews were able to render, so I think it would be better if I could wait for the Layout to render and then render the Page, but do you know how to implement this?
As per my understanding Mendix built one page application and Layout and page is one page .
In Mendix by default page shows once all the data widgets loads then it will show .
If you want to change the default behaviour you need to do lots of changes like based on some attributes you can enable the visibility
