    Undefined variable: _SESSION when extending LeftAndMain Link to this post

    I am trying to write a podcasting module, and am stuck at, well, the beginning. I started by copy and pasting the subclassing info here: http://doc.silverstripe.com/doku.php?id=leftandmain
    <br >
    <br >into a blank module folder structure.
    <br >
    <br >the class causing problems looks like this:
    <br >

    <br >class Podcaster extends LeftAndMain {
    <br >
    <br >static $url_segment = 'Podcasts';
    <br >static $menu_title = 'Podcasts Admin';
    <br >static $menu_priority = 60;
    <br >
    <br >
    <br >   static $template_path = null; // defaults to (project)/templates/email
    <br >   
    <br >   static $allowed_actions = array(
    <br >   );
    <br >
    <br >   
    <br >   static $url_rule = '/$Action/$ID/$OtherID';
    <br >   
    <br >
    <br >
    <br >
    <br >
    <br >   /**
    <br >    * Initialisation method called before accessing any functionality that BulkLoaderAdmin has to offer
    <br >    */
    <br >   public function init() {
    <br >      Requirements::javascript('cms/javascript/MyAdmin.js');
    <br >      
    <br >      parent::init();
    <br >   }
    <br >
    <br >   /**
    <br >    * Form that will be shown when we open one of the items
    <br >    */   
    <br >   public function getEditForm($id = null) {
    <br >      return new Form($this, "EditForm",
    <br >         new FieldSet(
    <br >            new ReadonlyField('id #',$id)
    <br >         ),
    <br >         new FieldSet(
    <br >            new FormAction('go')
    <br >         )
    <br >      );
    <br >   }
    <br >}
