Collapse nor JS calendar work when JS aggregator is enabled

did you include the code inside your page.tpl.php file just before <?php print $scripts; ?>?

<?php 
  if(module_exists('javascript_aggregator')) { 
    $scripts = javascript_aggregator_cache($scripts); 
  }

  print $scripts;
?>

Try clearing your JavaScript cache? Are you still running into this problem?

Mind trying this with 1.5?

Yay!
