Indirectly inherited class push_back's to std::vector

Here is the pseudocode:

Code:

---

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

Code:

---


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...

Code:

---

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:

Code:

---

#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); 
  }
};

---

Code:

---

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.

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!
