[xsd-users] Access Violation

[bruno.marotta at fortis.com]

Find out the solution (but it does make too much sense). If a create the object explicitely it works:

obj.action(xml::action((xml::action::value)at));

in the place of

obj.action((xml::action::value)at);

Regards

Hi,

I have a very simple class automatically generated by cxx tree, that when instantiated like this:

obj.action((xml::action::value)at);

raises an Access Violation... 

at is an integer and its current value is 17. From the call stack it seems that the error occurs when freeing a temporarily created action instance...

Here follows the class definition:

  class __declspec(dllexport) action: public ::xml_schema::string
  {
    public:
    enum value
    {
      New,
      LimitCheck,
      Exercise,
      Expiry,
      BarrierHit,
      Cancel,
      CancelAndReissue,
      Restructure,
      EarlyTermination,
      Fixing,
      Unwind,
      CancelOfMO,
      Novation,
      Netting,
      AddTrial,
      Update,
      Delete,
      OtherContractEvent
    };

    action ();

    action (value v);

    action (const ::xml_schema::string& v);

    action (const ::xercesc::DOMElement& e,
            ::xml_schema::flags f = 0,
            ::xml_schema::type* c = 0);

    action (const ::xercesc::DOMAttr& a,
            ::xml_schema::flags f = 0,
            ::xml_schema::type* c = 0);

    action (const ::std::string& s,
            const ::xercesc::DOMElement* e,
            ::xml_schema::flags f = 0,
            ::xml_schema::type* c = 0);

    action (const action& x,
            ::xml_schema::flags f = 0,
            ::xml_schema::type* c = 0);

    virtual action*
    _clone (::xml_schema::flags f = 0,
            ::xml_schema::type* c = 0) const;

    action&
    operator= (value v);

    virtual
    operator value () const
    {
      return _xsd_action_convert ();
    }

    protected:
    value
    _xsd_action_convert () const;

    public:
    static const char* const _xsd_action_literals_[18];
    static const value _xsd_action_indexes_[18];
  };

The class code:

  // action
  // 

  action::
  action ()
  : ::xml_schema::string ()
  {
  }

  action::
  action (value v)
  : ::xml_schema::string (_xsd_action_literals_[v])
  {
  }

  action::
  action (const ::xml_schema::string& v)
  : ::xml_schema::string (v)
  {
  }

  action::
  action (const action& v,
          ::xml_schema::flags f,
          ::xml_schema::type* c)
  : ::xml_schema::string (v, f, c)
  {
  }

  action& action::
  operator= (value v)
  {
    static_cast< ::xml_schema::string& > (*this) = 
    ::xml_schema::string (_xsd_action_literals_[v]);

    return *this;
  }

I hope you can help me.
