Fatal error: Uncaught Error: Call to a member function get() on null.

[Jonathan Lahijani]

<?php namespace ProcessWire;
class MyCoolModule extends WireData implements Module, ConfigurableModule {

	public function __construct() {
	    $this->myvar = $this->wire('pages')->get(2)->name; // problematic for some reason
	}

I have the above code in my module.  However it throws this error: Fatal error: Uncaught Error: Call to a member function get() on null.

Why is this the case?

Could you replacing the line with this:

$this->myvar = $this->pages->get(2)->name; // problematic for some reason

I have a note in my Processwire notes that say's

--Extend WireData to access API variables using $this->page instead of calling wire() function every time. It also lets us get module settings directly using $this->someSetting.
