Create an App with Advanced Page Building

Hi, I just started with Mendix and I am working on a learningpath with the module “Create an App with Advanced Page Building". According to the intructions I made Pages and two entitties .I don't use any security, but there are several users roles in the system. When i do a local run, there is nothing on my pages. However when I use the Account_overview page from the App Store module, II see all the Userroles wich are in the system. Is here someone who can help me?   Account_overview page

That is because the Account_Overview retrieves the accounts from the Entity Administration.Account and you want to retrieve your data from TeamMember.

I suggest you to add a Create Object button to your page, so you can insert data into the TeamMember entity.
This course can tell you more about that:
