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 >}
<br >

<br >
<br > When i try to build the database i get this:
<br >
<br >
<br >[Notice] Undefined variable: _SESSION
<br >GET /

<br >123 
<br >124 		// Return code for a redirection request
<br >125 		if(is_string($result) && substr($result,0,9) == 'redirect:') {
<br >126 			$response = new HTTPResponse();
<br >Trace

<br >Line 122 of main.php

<br >I really can't even thing where to start, and i've checked all of the usual causes of problems (cases, php file naming.)
<br >
<br >Can anyone help?

<br >Thanks.

<br >Yeah forget it, I'm trying this another way...
