Self referencing loop detected for property 'ManifestModule'
Can you add code for the classes Variant and ListingDates. Do they have navigation properties going both ways?

Hi Daniel,
No, they don't - the ProductListingDateRange class has just 3 properties:
public class ProductListingDateRange
{
public virtual string MarketId { get; set; }
public virtual DateTime? ListedFrom { get; set; }
public virtual DateTime? ListedTo { get; set; }
}
And the variant class exposes a collection of these as an IEnumerable.
Thanks

I had a similar issue and I solved it by using the NestedFilter property on my NestedFilterExpression
So try changing your return statement to this.
return new FilterExpression<IContent>(x =>
x.MatchType(typeof(Variant.Models.Variant)) &
((Variant.Models.Variant)x).ListingDates.MatchItem(item => exp.NestedFilter));

Hi,
We are getting the same error stacktrace described in this post:
http://world.episerver.com/forum/developer-forum/EPiServer-Search/Thread-Container/2014/8/Indexing-issues/
But we're getting it when attempting to do a nested search in Find. We have a nested convention applied:
Where listing dates is a collection of a custom object type.
And in the search query:
DateTime now = DateTime.Now; var exp = new NestedFilterExpression(
item => item.ListingDates,
item => item.ListedFrom.Exists() & item.ListedFrom.LessThan(now) & item.ListedTo.Exists() & item.ListedTo.LessThan(now),
SearchClient.Instance.Conventions);
return new FilterExpression(x =>
x.MatchType(typeof(Variant.Models.Variant)) &
((Variant.Models.Variant)x).ListingDates.MatchItem(item => exp)); It blows up with the error text 'Self referencing loop detected for property 'ManifestModule' - the JSON.NET serializer seems to be choking on a recursive reference within the Assembly, though why it's trying to serialize the assembly I have no idea!
Any pointers appreciated as to whether this is a bug or a problem with the way we're using Find.
