We have closed this ticket because another page addresses its subject:

Core - ApplicationUser reference property does not appear in ListView when the InstantFeedback mode is used

Missing data of reference columns of application user type when DataAccessMode = InstantFeedback

created 7 days ago

Greetings DevExpress team,

In our application built with DevExpress XAF Blazor, we have created a new entity called Ticket. This entity contains two navigation fields of type ApplicationUser, which we intend to use for assigning a ticket to an agent who is also a user of the application.
In the ListView of the Ticket entity, we have set DataAccessMode = InstantFeedback because we expect a large number of records and want to leverage the speed provided by this mode.
While these two fields function correctly in the DetailView of the ticket (i.e., the dropdown combos appear as expected, allowing user selection, and the values are saved properly upon submission), they appear empty in the ListView of the Ticket entity. At the same time, the filters for these empty columns work as expected.
Attached, you will find some screenshots illustrating the issue, as well as a sample project that you can use to reproduce it.
We eagerly await your response.

Regards,
Vassilios

      Hello Vassilios,

      Thank you for your patience.

      We reproduced this issue and created the following thread: Core - ApplicationUser reference property does not appear in ListView when InstantFeedback mode is used. We'll investigate it and update that thread once we have news.

      As a workaround, you can add the Browsable attribute to the ApplicationUser class:

      C#
      [Browsable(true)] // workaround
[DefaultProperty(nameof(UserName))]
public class ApplicationUser : PermissionPolicyUser, ISecurityUserWithLoginInfo, ISecurityUserLockout {
  // ...
}

      Regards,
      Fhillip
