In the function

	 * Overloaded load function
	 * @param       int $pk primary key
	 * @param       boolean $reset reset data
	 * @return      boolean
	 * @see JTable:load
	public function load($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');
			$this->params = $params;
			return true;
			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 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 does not look like a critical error.

The first 28 lines of the file admin\views\helloworld\tmpl\edit.php should look like this, as shown in the tutorial. <?php // No direct access defined('_JEXEC') or die('Restricted access'); JHtml::_('behavior.tooltip'); JHtml::_('behavior.formvalidation'); $params = $this->form->getFieldsets('params'); ?> <form action="<?php echo JRoute::_('index.php?option=com_helloworld&layout=edit&id='.(int) $this->item->id); ?>" method="post" name="adminForm" id="helloworld-form" class="form-validate">

<fieldset class="adminform"> <legend><?php echo JText::_( 'COM_HELLOWORLD_HELLOWORLD_DETAILS' ); ?></legend>

  • <?php foreach($this->form->getFieldset('details') as $field): ?>
  • <?php echo $field->label;echo $field->input;?>
  • <?php endforeach; ?>


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 ;-(
