Error C3254 compiling template class

Hi!

I have the following quite simple helper class to use with for_each to add 2D points to a 2D or 3D point vector. I have compiled this many times, but after some minor code change I suddenly get compiler error "error C3254: 'MyClass' : class contains explicit override '()' but does not derive from an interface that contains the function declaration" and can't see why? Any tips appreciated!
    template <class P>
    class solutionAdd
    {
    public:
      solutionAdd(std::vector<P>& solutions, const double elevation = 0.0) : 
         m_solutions(solutions), m_elevation(elevation) {}
      void operator()(const std::pair<double, Point2D>& breakPoint)
      {
        m_solutions.push_back(breakPoint.second);
      }
    private:
         std::vector<P>& m_solutions;
         double m_elevation;
    };
    template<> 
     void solutionAdd<Point3D>::operator()(const std::pair<double, Point2D>& breakPoint) 
    { 
      m_solutions.push_back(Point3D(breakPoint.second.GetX(), breakPoint.second.GetY(), m_elevation));
    }

I'm certainly overlooking something obvious here...

And as soon as I wrote this I found the error: I had moved this from outside the declaration of "MyClass" _into_ the class declaration...
