I'm getting this exception (Full exception at the bottom):
NHibernate.PropertyValueException was unhandled by user code
Message="not-null property references a null or transient
valueClearwave.Models.Encounters.Insurance.Patient"
Source="NHibernate"
EntityName="Clearwave.Models.Encounters.Insurance"
PropertyName="Patient"
I've done a lot of Googling and it seems the most common cause for
that error is when an association is bi-directional but only one half
has been set. As in: Insurance.Patient = Patient is called but
Patient.Insurances.Add(Insurance) is not. I do, in fact, have a
scenario like that but I've checked the object just before calling
Save with it and both Insurance.Patient and Patient.Insurances[0] are
the right objects.
The other possibility that this exception seems to reference is a
transient value. In my case *every* object is transient so I'm
suspecting the root of my problem is here. However, everything needs
to be transient right now because nothing has been saved yet. I would
expect NHibernate to persist things rather than complain that they are
not persisted.
Here are some snippets from my mappings (fluent):
public PatientMap()
{
WithTable("tPatient");
Id(x => x.Id, "uid_Patient").GeneratedBy.GuidComb
().Access.AsReadOnlyPropertyThroughCamelCaseField();
HasMany(x => x.Insurances).WithKeyColumn("uid_Patient")
.Cascade.All()
.Inverse();
...
}
public InsuranceMap()
{
WithTable("tPatientInsuranceInfo");
Id(x => x.Id,
"uid_PatientInsuranceInfo").GeneratedBy.GuidComb
().Access.AsReadOnlyPropertyThroughCamelCaseField();
References(x => x.Patient, "uid_Patient").Not.Nullable
().Cascade.All();
...
}
So, what could be the issue?
