The object mapper by default sets all PK fields to ReadOnly.
 
In many cases in our application we are passing the values for the PK to the create method on a Business Object class.
 
In the example below ComponentId is the PK of IOComponentOption.  How do I set this without changing all the field definitions in the Object Mapper for 500+ business objects?  I assume I can use the SetColumnValue method but this is a lot of code to rewrite for almost every business object.
 
EXAMPLE:
 

public static IOComponentOption Create(int componentId){

   IOComponentOption option = Session.PM.CreateEntity<IOComponentOption>() as IOComponentOption;

   option.ComponentId = componentId;

   option.Data = String.Empty;

   option.AddToManager();

   return(option);

}

I am not completely sure what you are trying to do, but you may find this trick helpful.  Assume emp is an Employe

emp.id = 22
 
gives compiler error.  "Property Id is read-only";
 
but
 
emp["Id"] = 22;
 
compiles and assigns 22 to Id property;
 
You can also use:
 
emp[0] = 22;
