I have the following Entity Framework model:

Entities

It’s a very simple model and was working fine when Entity Framework was generating the SQL. When I mapped the entities to stored procedures I get the following error when trying to create a LogEntry:

Unable to determine a valid ordering for dependent operations. Dependencies may exist due to foreign key constraints, model requirements, or store-generated values.

The code I am using to make a LogEntry looks like the following:

le.DateAndTime = DateTime.Now;
le.User = (Guid)Membership.GetUser().ProviderUserKey;

Log log = lr.GetLog(le.LogId);
log.LogEntries.Add(le);

lr.Save(); // lr is an instance of LogsRepository, defined earlier in the class

The exception isn’t thrown until lr.Save() is called.

Can anybody help me decipher this? I have stored procedures which all work on their own, independent of entity framework, mapped to the entities.

    I managed to figure out what was causing the error. Take a look at the following mapping setup:

    Log Mapping

    As you can see, I had a result column binding from UpdateLog, problem being that UpdateLog doesn’t return anything. I accidentally put this into the mapping. After deleting the result column binding everything works again.
