$300 Bounty - Gmap Field Module: Views integration needs 'finishing'.

Unfortunately all the necessary fields to display the map are not views. A way to ensure the presence of locations fields is load node. Replace function _gmapfield_get_markers in gmapfield.module by:

<?php
/**
 * Function to get markers
 *
 * @params $node
 *  Node object loaded so far
 * @params $field
 *  Field data
 * @return
 *  Associative array to merge into a gmap array
 */
function _gmapfield_get_markers($node, $marker, $field) {
  $loc_data = array();

  // Check for datasource
  if ($field['coordinate_datasource'] == 'location') {
    // Check Markers
    $available_markers = gmap_get_marker_titles();
    if (!array_key_exists($marker, $available_markers)) {
      $marker = 'drupal';
    }
    $node = node_load($node->nid);
    // Check for locations
    if ($locations = $node->locations) {
      $count = 0;
      foreach ($locations as $l) {
        // Check for lat and long first
        if ($l['longitude'] != 0 && $l['latitude'] != 0) {
          // Add markers
          $loc_data['markers'][] = array(
            'text' => theme('gmapfield_markerwindow', $l, $node),
            'longitude' => (float) $l['longitude'],
            'latitude' => (float) $l['latitude'],
            'markername' => $marker,
            'offset' => $count,
          );
          // Set center if primary or first location
          if ($l['is_primary'] || $count == 0) {
            $loc_data['longitude'] = $l['longitude'];
            $loc_data['latitude'] = $l['latitude'];
          }
          $count += 1;
        }
      }
    }
  }
  elseif ($field['coordinate_datasource'] == 'cck_fields') {
    $loc_data = array();
  }
  return $loc_data;
}

?>
