Insert will store a value marked as readonly. Update will not.

[jchannon]

If I create a ClassMapper and mark a property as ReadOnny() but then specify a value on my object and call db.Insert(myObj) it will insert the data with the specified value.

If I instantiate a object, set the marked Readonly property to a value and call db.Update(myObj) it won't update that field in the database.

Looking at the code Update filters out the properties marked as ReadOnly but Insert doesn't
