In the function

	/**

	public function load($pk = null, $reset = true) 
	{
		if (parent::load($pk, $reset)) 
		{
			// Convert the params field to a registry.
			$params = new JRegistry;                 
                       // loadJSON is @deprecated    12.1  Use loadString passing JSON as the format instead.
                       // $params->loadString($this->item->params, 'JSON');
//------------------------------------------------------------
                       $params->loadJSON($this->item->params);
//------------------------------------------------------------
 
			$this->params = $params;
			return true;
		}
		else
		{
			return false;
		}
	}

The line bracketed above is actually, $params->loadJSON($this->params); I am not sure which is 100% correct.

Just done a quick test and the one WITHOUT the 'item' is correct.

After changing files from 0.12 to 0.13 and downloading part13.zip I can't reach FrontEnd of HelloWorld component. I receive erorr 500. :( CodeBY 04:48, 4 May 2012 (CDT)

missing </fieldset> in admin\views\helloworld\tmpl\edit.php

It is not a critical error.

Looking at line 27 in the file admin\views\helloworld\tmpl\edit.php should look like this, as shown in the tutorial.

            </fieldset>

The file in the zipfile is missing this line </fieldset> (line 27)

Another minor detail is that the page on the website shows blocks of <?php ... ?> whereas the file as the php open and close per line.

Does not influence the working. But is good to know when comparing your code. I use winmerge to compare my files with those in the zip file. Hoping to find that typo that prevents my version from running as it should ;-(
