Hi!

After installing update 1 I see some changes in .h and .cpp files, generated
after editing tlb. Some types like IProvider* was changed on IProviderPtr.
Ok. But after that, when client run application server and try get provider
(for example, Table1 in RDM), apps server throw exception.

it's happend because casting NOT work properly in the following code:

STDMETHODIMP TTest1Impl::get_Table1(IProviderPtr* Value)
{
  try
  {
  _di_IProvider IProv = m_DataModule->Table1->Provider;
  IProv->AddRef();

  *Value = IProv;        // !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

  }
  catch(Exception &e)
  {
    return Error(e.Message.c_str(), IID_ITest1);
  }
  return S_OK;
};

after changing this string:

  *Value = (IProviderPtr)IProv;

all work fine. Where is a bug? In automatic code generation or else?

This is a known bug in the code generation.  I had hoped it would have
been fixed in the second patch, as it seems pretty straightforward to
fix.  Oh well.
