[T5] Null fields and BeanEditForm?

[Tom Davies]

I'd like to be able to have optional values in a BeanEditForm linked  
bean represented as null, e.g. if they are of type Integer.

I get the exception below.
Should 'null' just coerce straight to null, unless it is trying to go  
to a primitive type?

In TypeCoercerImpl, perhaps:

// Treat null as void in terms of locating a coercion.

        Class sourceType = input != null ? input.getClass() :  
void.class;

Should be: (untested)

        if (input == null)
        {
                if (targetType.isPrimitive())
                {
                    throw ...
                }
                else
                {
                    return null;
                }
        }
