Fatal error: Call to a member function setFlags() on a non-object in /class_appcontroller.php

Don't believe that was the issue:

Believe the issue is in the constructor of myadopts.php

if( $this->action != "index"){
				try{
					$this->adopt = new OwnedAdoptable($mysidia->input->get("aid"));	
					if($this->adopt->getOwner() != $mysidia->user->username) throw new NoPermissionException("permission");		
					$this->image = $this->adopt->getImage("gui");
				}

if( $this->action != "index"){, if the page isn't index page of myadopts/, it tries to fetch a pet id ? =)
