Hi Forum, I cannot understand 1. why here I was asked to change the Name 2. why shall I create UserRole_Select here In the Data view you just created, change the Label caption of Name to Username. Double-click the User role selection widget to configure it. Change the Data source to Name rather than ModelGUID. Change the Editability setting to Default. At the top of the window, change the Select page by clicking Select…. In the Select web page window, create a new page called UserRole_Select using the PopupLayout navigation layout and the Select With List View template. Mendix will create this for you. Click OK. Click OK again.
