Call to parent issue - I think 16 Dec 2016 03:24 #14849

vlemos Online Elite Member Posts: 295 Thank you received: 41 Karma: 21	Hello Admin / Cooks I have a forked "replaced" controller class. However, I believe that the line: $this->_result = $result = parent::cancel(); is defeating my routine by referencing "parent". Has anyone had a similar experience in a controller? In a rush towards a deadline and don't have the time to research it fully. Feedback appreciated Thanks alot vlemos

Hello liubov / cooks

The simplest solution I implemented was to call the class directly. However, I added a class alias to the constructor for "_parent" and then replace parent::cancel() with _parent::cancel(). Note: you must first determine the class being called by the child.

Hope this helps some other cook working with the fork controller classes.

Warm regards

	 *
	 * @return	void
	 */
	public function __construct($config = array())
	{
		parent::__construct($config);
		$app = JFactory::getApplication();

		class_alias('TestCkClassControllerItem', '_parent');

	}

	//Usage 
	$this->_result = $result = _parent::cancel();

Hello Admin

The fork framework needs revisiting as it relates to the reference "parent". Once "parent::" is called within a forked class, execution passes to the main class and never returns. Therefore forking some routines is useless. For a forked field (cktext.php), when "return parent::getInput();" is called, the input property is overwritten by the main routine.

	/**
	* Method to get the field input markup.
	*
	* @access	public
	*
	*
	* @since	11.1
	*
	* @return	string	The field input markup.
	*/
	public function getInput()
	{

		$this->input = JDom::_('html.form.input.text', array_merge(array(
				'dataKey' => $this->getOption('name'),
				'domClass' => $this->getOption('class'),
				'domId' => $this->id,
				'domName' => $this->name,
				'dataValue' => $this->value,
		'testValue' => $this->test,
				'placeholder' => $this->getOption('placeholder'),
				'prefix' => $this->getOption('prefix'),
				'responsive' => $this->getOption('responsive'),
				'size' => $this->getOption('size'),
				'suffix' => $this->getOption('suffix')
			), $this->jdomOptions));

		return parent::getInput();
	}

Please look into this and let me know if it can be easily fixed across components.
