Unable to cast object of type 'System.Linq.Expressions.UnaryExpression' to type 'IQToolkit.Data.Common.ColumnExpression'.

[toSilence]

Hi,

i get an error during using IQToolkit.
I have a Datacontext with two items Offer and OfferItems.

Both are connected together:
Offer has OfferItems
OfferItem has Offer

Context:

public partial class Offer {
public IList OfferItems { get; set; }
}

public partial class OfferItem {
public Offer Offer1 { get; set; }
}

Pseudo code:

policy.IncludeWith(o => o.OfferItems);
policy.IncludeWith(o => o.Offer1);

var q1 =
from l in db.OfferItems
select l;
=> working

var q2 =
from l in db.Offers
select l;
=> failed

I tried to change the policy to policy.IncludeWith(o => o.OfferItems, true); but got another exception.
If I change the context IList to OfferItem the linq query is working but not correct.

Any help appreciate.

Thx in advance.
