Hi Robbie,

I did not support nuPickers. This is because the data in nuPickers isn't necesarry Umbraco Content. You can connect to all types of data sources with nuPickers.

But I made nexu extensible so you can add your own parsers : https://github.com/dawoe/umbraco-nexu/blob/develop/docs/extending.md

Here you have some example code of a parser for a nuPickers datatype that stores the valuas as CSV. After you added this to your project you need to register it with Nexu. You can find that in the docs.

public class CategoryPickerSinglePropertyParser : IPropertyParser
    {       
        public bool IsParserFor(IDataTypeDefinition dataTypeDefinition)
        {
            // check on the name of your nupickers type
            return dataTypeDefinition.Name.Equals("Category picker single");
        }

        public IEnumerable<ILinkedEntity> GetLinkedEntities(object propertyValue)
        {
            if (propertyValue == null || string.IsNullOrEmpty(propertyValue.ToString()))
            {
                return Enumerable.Empty<ILinkedEntity>();
            }

            var entities = new List<ILinkedEntity>();

            var idArray = propertyValue.ToString().Split(new[] { ',' }, StringSplitOptions.RemoveEmptyEntries);

            foreach (var id in idArray)
            {
                var attemptId = id.TryConvertTo<int>();

                if (attemptId.Success)
                {
                    entities.Add(new LinkedDocumentEntity(attemptId.Result));
                }
            }

            return entities;
        }
    }
