When you goes to the Hotel Availability Calendar page. The title always show the current month even i am browsing other months.

I found the following error when i try to print the $ref_dt on hotel_booking.calendars.inc on line 41.

<?php
DateObject Object
(
    [
granularity] => Array
        (
            [
0] => hour
           
[1] => minute
           
[2] => second
           
[3] => month
           
[4] => day
           
[5] => year
           
[6] => timezone
       
)

    [
errors] => Array
        (
            [
invalid] => The value 2013-11-01 does not match the expected format.
        )

    [

    [
serializedTimezone:DateObject:private] =>
    [

    [
dateOnly] =>
    [
originalTime] => 2013-11-01
   
[date] => 2012-12-31 00:49:48
   
[timezone_type] => 3
   
[timezone] => Asia/Hong_Kong
)
?>

The date string is not in DATE_FORMAT_ISO when creating the $ref_dt object.

To fix the problem, use the following date formatter.

<?php
function hotel_booking_availability_form($form, $form_state, $node, $year = NULL, $month = NULL) {
  if (!
$node || $node->type != 'hotel_room_type') {
    return
drupal_not_found();
  }
  if (
$node->tnid && $node->nid != $node->tnid) {
   
drupal_set_message(t('This room is part of a translation set, availability can only be set against the
                         translation master, you have been redirected to the translation master to edit the availability'
));
   
drupal_goto('node/'. $node->tnid .'/availability');
  }
 
//set up defaults
 
if (!$year) {
   
$year = date('Y');
  }
  if (!
$month) {
   
$month = date('m');
  }

  if (!
is_numeric($year) || !is_numeric($month)) {
    return
drupal_not_found();
  }

 
/* FIX */
  //$ref_dt = new DateObject("$year-$month-01", date_default_timezone(), DATE_FORMAT_ISO);
 
$ref_dt = new DateObject("$year-$month-01", date_default_timezone(), 'Y-m-d');
?>
