Disabling action buttons in lazily loaded screen

washi · February 21, 2026, 7:31pm

Version 2025.10.2.

When designing lazily loaded screen if the user decides to disable action buttons on the root screen section the frontend doesn’t display the screen and instead returns following error message:

Error: Cannot infinitely scroll on dataStructureEntity: d211c7e1-9954-46ae-ac06-80c7147f08a4 because it has no default ordering on the displayed form.

Enabling the action buttons on the root screen section is a workaround, but the disabling the action buttons shouldn’t cause with ordering of the screen.

It looks like the behavior is caused by this line, and the line have been there since the first commit.

          panel.Entity = element.GetAttribute("Entity");
          panel.Id = XmlConvert.ToGuid(element.GetAttribute("ModelId"));
          panel.InstanceId = XmlConvert.ToGuid(element.GetAttribute("ModelInstanceId"));
          if (element.GetAttribute("DefaultPanelView") != "") { }
          UIPanelConfig panelConfig = GetPanelConfig(workflowId, profile, data, panel, element);
          result.PanelConfigurations.Add(panelConfig);
          // default sort
          if (
              sortSet != null
              && element.AttributeIsFalseOrMissing("IsHeadless")
              && element.AttributeIsFalseOrMissing("DisableActionButtons")
          )
          {
              List<DataStructureSortSetItem> sorts = new List<DataStructureSortSetItem>();
              foreach (
                  var item in sortSet.ChildItemsByType<DataStructureSortSetItem>(
                      DataStructureSortSetItem.CategoryConst
                  )
              )
              {
                  if (item.Entity.Name == panel.Entity)

@tvavrda Do you think we can remove this line?
