Issue arises when Examine is indexing grid nodes with DTGE and Nested Content content that are also indexed; Umbraco 7.3.

Grid content is being indexed using Skybrud.Umbraco.GridData package with this pull request and this gist.

Doc type models are generated using ZpqrtBnk Umbraco Models Builder with a modified PublishedContentModel to handle exceptions (e.g. picker with no value).

    using System;

    using Umbraco.Core.Logging;
    using Umbraco.Core.Models;
    using Umbraco.Web;

    public class PublishedContentModel : Umbraco.Core.Models.PublishedContent.PublishedContentModel
    {
        public PublishedContentModel(IPublishedContent content)
            : base(content)
        {
        }

        public T GetPropertyValue<T>(string alias)
        {
            try
            {
                if (this.Content.HasProperty(alias) && this.Content.HasValue(alias))
                {
                    return PublishedContentExtensions.GetPropertyValue<T>(this.Content, alias);
                }
                else
                {
                    return default(T);
                }
            }
            catch (Exception exception)
            {
                LogHelper.Error<IPublishedContent>(
                    string.Format("Name: {0} - Alias: {1}", this.Content.Name, alias), 
                    exception);
                return default(T);
            }
        }
    }

@nvisage-gf Could you add the previewViewPath line back in please? Thanks.

@nvisage-gf All looks good, thanks!

Although I think you'll need to rebase on the latest commits - I'd just merged in PR #17 - which causes a merge conflict for your PR.

done
