CIMStandaloneTable.FieldDescriptions property allways return null in ArcGis Pro 3.0

StephenCochrane

I have this C# function to retrieve the CIMFieldDefinitions from a standalone table. It worked fine in the Pro 2.9.x but after migrating to Pro 3.0 it seems that FieldDescriptions property on the CIMStandaloneTable class is always null.

 

public CIMFieldDescription[] GetCIMFieldDescriptions(StandaloneTable table)
{
CIMStandaloneTable cimTableDefinition = null;
QueuedTask.Run(() =>
{
cimTableDefinition = table.GetDefinition() as CIMStandaloneTable;
});
return cimTableDefinition.FieldDescriptions;
}

 

Is something wrong with this code? Or is this an issue for Pro 3.0?

I tried the following on both 2.9 and 3.0 and it seems to work (no  FieldDescription == null is returned):

protected override async void OnClick()
{
  var mapMembers = MapView.Active.Map.GetLayersAsFlattenedList().OfType<MapMember>();
  var result = await QueuedTask.Run<string>(() =>
  {
    StringBuilder sb = new StringBuilder();
    foreach (var mapMember in mapMembers)
    {
      sb.AppendLine($@"member: {mapMember.Name} is Standalone: {mapMember is StandaloneTable} is BasicFeatureLayer {mapMember is BasicFeatureLayer}");
      if (!(mapMember is StandaloneTable || mapMember is BasicFeatureLayer)) continue;
      var dispTable = mapMember as IDisplayTable;
      var fieldDescriptions = dispTable.GetFieldDescriptions();
      foreach (var field in fieldDescriptions)
      {
        field.IsVisible = true;
      }
      sb.AppendLine($@" => table: {dispTable.GetTable().GetName()} fields: {fieldDescriptions.Count}");
      dispTable.SetFieldDescriptions(fieldDescriptions);
    }
    return sb.ToString();
  });
  mapMembers = MapView.Active.Map.GetStandaloneTablesAsFlattenedList().OfType<MapMember>();
  result += await QueuedTask.Run<string>(() =>
  {
    StringBuilder sb = new StringBuilder();
    foreach (var mapMember in mapMembers)
    {
      sb.AppendLine($@"member: {mapMember.Name} is Standalone: {mapMember is StandaloneTable} is BasicFeatureLayer {mapMember is BasicFeatureLayer}");
      if (!(mapMember is StandaloneTable || mapMember is BasicFeatureLayer)) continue;
      var dispTable = mapMember as IDisplayTable;
      var fieldDescriptions = dispTable.GetFieldDescriptions();
      foreach (var field in fieldDescriptions)
      {
        field.IsVisible = true;
      }
      sb.AppendLine($@" => table: {dispTable.GetTable().GetName()} fields: {fieldDescriptions.Count}");
      dispTable.SetFieldDescriptions(fieldDescriptions);
    }
    return sb.ToString();
  });
  MessageBox.Show(result);
}
