Adding multiple SortParameters - .Net API

Question

Tridion 2011 SP1 HR2

I am having trouble getting multiple sort orders added via the .Net api.

We have multiple custom meta fields as below:

Order Items (Added in this order)

FieldName          FieldType            MetaDataType     Order

resource_category    Category             String         Asc
year                 Category             String         Asc
resource_material    Category             String         Asc

Query

using (var query = new Tridion.ContentDelivery.DynamicContent.Query.Query(criteriaBuilder.Criteria))
{
    if (orders != null)
    {
        foreach (var item in orders)
        {
            var sort = new CustomMetaKeyColumn(item.FieldName, item.MetaDataType);
            query.AddSorting(new SortParameter(sort, item.Ascending ? SortParameter.Ascending : SortParameter.Descending));
        }
    }
    var ids = query.ExecuteQuery();
    
    return ids;
}  

Example data:
Resource1 | A Category | 1941 | Report
Resource2 | B Category | 1981 | Report
Resource3 | A Category | 1984 | Document
Resource4 | B Category | 1980 | Report

Expected Result:
Resource1 | A Category | 1941 | Report
Resource3 | A Category | 1984 | Document
Resource4 | B Category | 1980 | Report
Resource2 | B Category | 1981 | Report

Actual Result:
Resource3 | A Category | 1984 | Document
Resource1 | A Category | 1941 | Report
Resource2 | B Category | 1981 | Report
Resource4 | B Category | 1980 | Report

In other words it only applies the last sort parameter applied.

There was mention in another post that this was a known issue See Here but that was July last year.

I am having issues trying to access the support system and can not find mention of this in the live docs etc so thought I would ask here.

Does anyone know if there has been an update to this or perhaps another way of implementing this via the api (trying to avoid dirtying custom code)

Thanks in advance

Answer 1

It was fixed in 2013; it has not been fixed for any version of 2011 as far as I know.
