Is the syntax right, in that we just have to name the field or is there more needed?

I've done some stepping through the code and it attempts to save the child in this code:

ChildResult = ChildBizObj.SaveEntityList();

and then here:

public override mmSaveDataResult SaveEntityList()
{
	return this.SaveEntityList(this.EntityList);
}

this.EntityList == null

How could that be?
