XhtmlString (MainBody) is null. How do I get the value?

Vote:

How come description is null? If I try to get the AsViewedByAnonymous I get an empty string. The text is clearly there, I just cant figure out how to get it!

The search:

public JsonResult Search(string searchString)
{

var allResults = SearchClient.Instance.Search<FactPage>().For(searchString)
.Filter(x => x.RolesWithReadAccess().Match("Everyone"))
.Select(x => new SearchHit
{
Heading = x.Name,
Type = "facts",
Description = x.MainBody.ToString(),
LinkUrl = x.LinkURL
})
.IncludeType<SearchHit, LessonPage>(x =>
new SearchHit
{
Heading = x.Name,
Type = "lesson",
Description = x.BodyOne.ToString(),
LinkUrl = x.LinkURL
})
.IncludeType<SearchHit, VideoBlock>(x =>
new SearchHit
{
Heading = x.H2Text,
Type = "videoblock",
Description = x.Description,
LinkUrl = x.VideoFileUrl.ToString()
})
.Track()
.Take(10)
.GetResult();

var results = new
{
all = allResults
};

return Json(results, JsonRequestBehavior.AllowGet);
}

The indexed Item(from find explorer)

Källdokument:

{
  "$type": "WebProject.Models.Pages.LessonPage, WebProject",
  "BodyOne": {
    "$type": "EPiServer.Core.XhtmlString, EPiServer",
    "IsEmpty$$bool": false,
    "IsModified$$bool": false,
    "___types": [

      "EPiServer.Data.Entity.IReadOnly"
    ],
    "AsViewedByAnonymous$$string": "Lamm är ett riktigt mört kött. Hemligheten för att få ett riktigt saftigt kött är att använda en stektermometer och inte laga på för hög värme. Förutom massa recept på saftiga lammrätter, hittar du också tips på hur du tillagar lammköttet på bästa sätt."

Hi,

Change: x.YYYBody.ToString() => x.YYYBody.AsViewedByAnonymous() in the Select statements.

Thanks Henrik (I had the ToString() method which I tried before posting to forum). The following example returns an empty text string using AsViewedByAnonymous().

public JsonResult Search(string searchString)
{var allResults = SearchClient.Instance.Search<FactPage>().For(searchString)
.Filter(x => x.RolesWithReadAccess().Match("Everyone"))
.Select(x => new SearchHit
{
Heading = x.Name,
Type = "facts",
Description = x.MainBody.AsViewedByAnonymous(),
LinkUrl = x.LinkURL
})
.IncludeType<SearchHit, LessonPage>(x =>
new SearchHit
{
Heading = x.Name,
Type = "lesson",
Description = x.BodyOne.AsViewedByAnonymous(),
LinkUrl = x.LinkURL
})
.IncludeType<SearchHit, VideoBlock>(x =>
new SearchHit
{
Heading = x.H2Text,
Type = "videoblock",
Description = x.Description,
LinkUrl = x.VideoFileUrl.ToString()
})
.Track()
.Take(10)
.GetResult();
var results = new
{
all = allResults
};return Json(results, JsonRequestBehavior.AllowGet);
}

I have tried to reindex the site as well.

Sometimes I get a first chance exception instead of empty string.. it looks like this. Is there a chance the AsViewedByAnonymous() returns something else than a string?

A first chance exception of type 'EPiServer.Find.ProjectionException' occurred in EPiServer.Find.dll

Additional information: Invalid operation while projecting search result item to type SearchHit with expression x => new SearchHit() {Heading = x.Name, Type = "lesson", Description = x.BodyOne.AsViewedByAnonymous(), LinkUrl = x.LinkURL}. The fields to bind were ___types, Name$$string, LinkURL$$string, MainBody. variable 'x' of type 'WebProject.Models.Pages.LessonPage' referenced from scope '', but it is not defined

x.YYYBody.AsViewedByAnonymous() should have worked, but it seems like there is an indifference in the field value specification.

To verify, you could try this super nasty hack (not recommended):

    public class Hack
    {
        public HackBody MainBody { get; set; }
        public class HackBody
        {
            public string AsViewedByAnonymous { get; set; }
        }
    }

and then

Description = ((Hack)(object)x).MainBody.AsViewedByAnonymous,

However, an easy fix to this would probably be to use x.YYYBody.AsCropped(int.MaxValue), unless Henrik has a clever trick up his sleeve. :-)

Ah! Thanks Magnus. The hack works.

I'm going for the AsCropped solution which does the trick :)
