      Sorry, and thank you for the link.

class A
{
  public:
    A(): _strA("A") {}
    std::string _strA;
};

class B : public A
{
  public:
    B(): _strB("B") {}
    std::string _strB;
};

Hi,
I would like to know why is'nt that working:
boost::ptr_vector<B> p1;
    boost::ptr_vector<B> p2;
    std::vector<B> v1;
boost::ptr_vector pview;
// add elements...
p1 = p2;
    pview = p1;
//    p1 = v1; // don't work
//    pview = v1; // don't work
It should be working, or would be interesting to get working.
Without seeing your A's and B's it's hard to tell, but I think you're
talking
about this....
