STL card does not add a pair after removing the first pairs

In this code snippet, I add a pair to the map and everything is fine, but when I remove a pair that is not the last, no more pairs are added in the map. What am I doing wrong?

SomeClass::add(Object object)
if (!object.empty())
{
    ObjectList::iterator result = find(object.name());
    if (result == ObjectList.end())
    {
        object.order(size() + 1);
        ObjectList.insert(orderedObject(object.order(), object));
    }
    else
    {
        ObjectList[result->first] = object;
    }
}

      

        
        
        
      

    

ObjectList and orderedObject are declared like this:

typedef std::pair<int, Object> orderedObject;
typedef std::map<int, Object> ObjectList;

      

        
        
        
      

    

This is the removal code:

SomeClass::eraseNamed(std::string aName)
{
    if (!isEmpty())
    {
        ObjectList::iterator result;
        result = find(aName);
        if (result != ObjectList.end())
        {
            ObjectList.erase(result);
            reorgObjectList();
            return true;
        }

    }
    return false;
}

      

        
        
        
      

    

For the search method:

ObjectList::iterator SomeClass::find(std::string aName)
{
    ObjectList::iterator result = ObjectList.begin();
    while (result != ObjectList.end())
    {
        if (aName == result->second.name())
            return result;
        result++;
    }
    return result;
}

      

        
        
        
      

    

and for reorgObjectList:

bool SomeClass::reorgObjectList()
{
    ObjectList::iterator i=ObjectList.begin();
    int j=1;
    for (i = ObjectList.begin(); i != ObjectList.end(); ++i)
    {
        if(j!=i->second.order())
            i->second.order(j);
        j++;
    }
    return true;
}

      

        
        
        
      

    

Any suggestions???
