Hi Boris,
Your Login_Overview page has a dataview on it for a Login object. But you will need to have to Login object available for the user to show this page, because it isn't avaible on the page the user currently is. So you need to figure out how a user can obtain the correct Login object to show that page.
That's possible though a nanoflow or microflow, where you Retrieve the Login object first and then with a Show Page action passes this object to the page. Think about data flowing through your application and when the right data is available.
Or perhaps modify your dataview on Login_Overview with microflow as datasource where you create a Login object as needed.
