Thanks, Bill ... that did it.

I would have thought that since I was calling create entity on the manager that it already knew about it :-/

Thanks again,

Phil

After creating comp, add it to the PersistenceManager cache

comp.AddToManager();

I have the following select query which works fine ...

DomainModel.Manager manager = new DomainModel.Manager();

var query = manager.Companies;

foreach (DomainModel.Company comp in query)

{

textBox1.Text += comp.CompanyName;

}

if (textBox1.Text.Length == 0)

{

MessageBox.Show("No Companies");

}

... but, I cannot create a new record ...

DomainModel.Manager manager = new DomainModel.Manager();

DomainModel.Company comp = manager.CreateEntity();

comp.CompanyName = textBox1.Text;

comp.CompanyId = 1;

List list = new List();

list.Add(comp);

SaveOptions options = new SaveOptions();

options.ThrowExceptionOnSaveFailure = ThrowExceptionRule.Always;

manager.SaveChanges(list, options);

... it runs fine (no errors), but it does not create a new record in the db. So, what am I doing wrong?
