Passing params to form component – value of params is null

Hi,

I have just solved a mystery that took me a lot of time. I am posting this as I think it could help someone.

I had this form as a component, and I wished to pass some params to it.

The component:

class EditForm extends UI\Control
{
	public $params;

	public function __construct($params)
	{
		parent::__construct();
		$this->params = $params;
		bdump($this->params); // (1) I will  write about this later
	}

	public function createComponentForm()
	{
		bdump($this->params); // (2) I will  write about this later

		$form = new UI\Form;

		/* form fields */

		$form->onSuccess[] = [$this, 'processForm'];

		return $form;
	}

	public function render()
	{
		$this->template->setFile(__DIR__.'/templates/editProgram.latte');
		$this->template->render();
	}

	/**
	 * @param UI\Form $form
	 */
	public function processForm(UI\Form $form)
	{
		/* some data processing code */
		$form->onSuccess;
	}
}

Its factory:

interface IEditProgramFormFactory
{
	/**
	 * @return EditProgramForm
	 */
	function create($params);
}

Which i call like this:

	$form = $this->editProgramFormFactory->create([/* some values*/])

At first look nothing out of ordinary, but when I tried to run it, the first bdump (1) returned the params as expected, but the second one (2) was returning null no matter what I have tried to do.

Finally i tried to rename the $params to something else (in my case $pamareters) and voilà it all has started to work normally.

Is $params some sort of “reserved variable”, or was doing something wrong?
