Do you mean putting Factory::selectShadowAlgorithm() in a transaction?

Why does (only) Factory::selectImageType() has its own callback?

bool Factory::selectImageType(const string& spec) const
{
  string name;
  vector<string> args;
  parseSpec(spec, name, args);

  ImageCreatorMapType::const_iterator iter = imageCreators.find(name);
  if(iter == imageCreators.end())
    return 0;

  ImageCreator creator = iter->second;

  // Create a static method callback.  
manta_interface->setCreateImageCallback( Callback::create( 
&Factory::createImageCallback,
                                                             creator,
                                                             args ) );
 
  return true;
}

void Factory::createImageCallback( bool stereo, int xres, int yres,
Image *& image, ImageCreator creator, vector<string> args ) {

  // Invoke the legacy image creator.
  image = (creator)(args, stereo, xres, yres);
}
