Indirectly inherited class push_back's to std::vector

[lucky6969b]

Here is the pseudocode:

class Object
{
};

class Goods : public Object
{
};

class Pallet : public Goods
{
    Pallet(const Pallet& _p) { this->mesh = _p.mesh; }
};


class myDX9Widget {
std::vector<Object*> m_vRenderObjects;
};

SkinnedMesh *palletMesh = new SkinnedMesh();
Pallet *pallet = new Pallet(palletMesh);

m_vRenderObjects.push_back(pallet);      // Error here

And BTW, if I need to use the copy constructor

 
class Lorry : public Object
{
     myDX9Widget *mOwner;
     Pallet *GeneratePallet() 
     {
        Pallet *pallet = new Pallet();   // should have used a copy constructor here, 
//but i don't have a reference of Pallet,
// anywhere I should store it if you were programming a warehouse simulator....
        return pallet;
     }
}

This is triggered when a TruckArrive Event happens...

class TruckArrive
{
    void OnUpdate(float dt)
    {
       if (m_blorryHasParked)
       {
          Lorry *lorry = dynamic_cast<Lorry*>(Actor);
          Pallet *pallet = lorry->GeneratePallet();
          lorry->mOwner->m_vRenderObjects.push_back(pallet);
       }
    }

}

Any comments are welcome!

1. Is it possible to create a small program that demonstrates the error ?
For example, the following compiles:

#include <vector>

class Object {};

class Goods : public Object {};

class Pallet : public Goods {};

class myDX9Widget 
{
   std::vector<Object*> m_vRenderObjects;

   void foo()
   {
      Pallet *pallet = new Pallet();

      m_vRenderObjects.push_back(pallet);  
   }
};

[2kaud]

SkinnedMesh *palletMesh = new SkinnedMesh();
Pallet *pallet = new Pallet(palletMesh);

m_vRenderObjects.push_back(pallet);      // Error here

To what function do these statements belong? - as posted they don't belong to any function which could be why you are getting an error.

Here is the pseudocode:

It would be much better if you posted the actual code rather than pseudocode so that we don't have to guess what your code is actually trying to do!
