The creation of the cycle works, but when I try to delete the cycle, I have 2 problems Before the delete statement, NHibernate does an update statement to set the Parent.Cycle to NULL.However this property is not nullable, because if the cycle does not have a parent it references to himself.When I make the property nullable another problem occurs.Nhibernate does the update which now succeeds but during this update it does not increment the version number.This is a problem for our auditing system.With every update the version should be incremented.Im wondering if anyone else had the same problems, the ideal solution would be to stop the update because it is unnecessary.But I cannot seem to achieve this.Github.
