Code

function init_display($reset = FALSE) {
  // The default display is always the first one in the list.
  if (isset($this->current_display)) {
    return TRUE;
  }

  // Instantiate all displays
  foreach (array_keys($this->display) as $id) {
    // Correct for shallow cloning
    // Often we'll have a cloned view so we don't mess up each other's
    // displays, but the clone is pretty shallow and doesn't necessarily
    // clone the displays. We can tell this by looking to see if a handler
    // has already been set; if it has, but $this->current_display is not
    // set, then something is dreadfully wrong.
    if (!empty($this->display[$id]->handler)) {
      $this->display[$id] = clone $this->display[$id];

      // Initialize the new display handler with data.
      $this->display[$id]->handler->init($this, $this->display[$id]);
      // If this is NOT the default display handler, let it know which is
      // since it may well utilize some data from the default.
      // This assumes that the 'default' handler is always first. It always
      // is. Make sure of it.
