Cannot find an appropriate constructor which map parameters in class

[Lee Shinlever]

Greetings,

 I have a class with two constructors such as:

 public class SomeClass
{
    protected SomeClass()
    {
        // empty constructor
    }

    public SomeClass(ridiculously long param list)
    {
        //...initialize private variables
    }
}

In my mapping file I have tried defining the ResultMap for the public
ctor using the <constructor> attribute but I keep getting the "Cannot
find an appropriate constructor which map parameters in class:
SomeClass".

Any ideas?

Thanks,
Lee
