Hi All,
I am using the new NHibernate Linq provider included in the trunk. I
am trying to execute a group join clause, however I have not succeeded
yet. The problem I'm dealing with is an "System.InvalidCastException"
thrown by "GroupJoinAggregateDetectionVisitor" class. The exception is
thrown by the first line of the method
"VisitQuerySourceReferenceExpression". The exception message is;
Unable to cast object of type
'Remotion.Data.Linq.Clauses.GroupJoinClause' to type
'Remotion.Data.Linq.Clauses.FromClauseBase'
The Linq expression related to the exception is as follows;
from c in DataRepository.DaoOf<ProductCategory>()
join p in DataRepository.DaoOf<Product>() on c.Id
equals p.ProductCategoryId into products
select new ProductCategoryView(c, products.ToList())
There are no problems related to either the models or the mapping
documents. What am I missing?
Thanks in advance.
Odul.
