InsertSortGroupField not completing???

[Anonymous]

Hi there,

I am trying to order my sorting and grouping in the Revit API. the transaction completes fine when i use the AddSortGroupField method but this always puts Type before Category when sorting. When I use the InsertSortGroupField method the transaction does not complete?

Snippet of the code below, Can anyone help?

if (schedulableField.FieldType == ScheduleFieldType.Instance)
                {
                                     //Add a new schedule field to the view schedule by using the SchedulableField as argument of AddField method of Autodesk.Revit.DB.ScheduleDefinition class.
                    String fieldname = schedulableField.GetName(document);
                    
                    if (fieldname == "Type")
                    {
                        ScheduleField fieldType = schedule.Definition.InsertField(schedulableField,1);
                        fieldType.GridColumnWidth = 4.0 / 12;
                        fieldType.HorizontalAlignment = ScheduleHorizontalAlignment.Left;
                        ScheduleSortGroupField TypeGroupField = new ScheduleSortGroupField(fieldType.FieldId);
                        schedule.Definition.InsertSortGroupField(TypeGroupField,1);
                        TypeGroupField.ShowHeader = false;
                    }
                        
                    if (fieldname == "Category")
                    {
                        ScheduleField fieldCat = schedule.Definition.InsertField(schedulableField,0);
                        fieldCat.GridColumnWidth = 4.0 / 12;
                           fieldCat.HorizontalAlignment = ScheduleHorizontalAlignment.Left;
                        ScheduleSortGroupField CatGroupField = new ScheduleSortGroupField(fieldCat.FieldId);
                        schedule.Definition.InsertSortGroupField(CatGroupField,0);
                        CatGroupField.ShowHeader = true;
                        fieldCat.IsHidden = true; 
                    }
                    
                    schedule.Definition.IsItemized = false;
                    schedule.Definition.ShowHeaders = true;
                  }
                         
                //Judge if the FieldType is ScheduleFieldType.Count.
                if (schedulableField.FieldType == ScheduleFieldType.Count)
                {
                     schedule.Definition.InsertField(ScheduleFieldType.Count,3);
                }
                
               }

Could not immediately spot anything wrong here... but are the indexes called at the correct order? (when you InsertField, the second parameter, index)

Also, when you say "transaction does not complete", does it throw any exception? Any kind of error message?
