Exception:"Persistent class 'X' was specified as candidate, but..."

Hi,

when I try to 'for each' on a IQueryResult I get:

InvalidOperaionException: "Persistent class 'Entities.Visit' was specified as candidate, but the ResultSet does not contain any/all of the pk columns."

Telerik.OpenAccess.dll is referenced. Exception throws in the foreach:

  IQuery sqlQuery = northwindScope.GetSqlQuery("SELECT * FROM tablename", typeof(classname), "");
IQueryResult result = sqlQuery.Execute();

foreach (classname v in result) yield return v; // InvalidOperaionExcepion thrown

Thanx if You have any idea

Ops...I had to upgrade to 2008.3.1327.2 and it's fixed. May it was a reverse engineering bug.
