Using isset() to check if model exists

[eluser]Unknown[/eluser]
Hi everyone,

I have a problem with my model that has been bugging me for quite a while now. Here's how my __construct method looks like:

Code:

private $is_team;

public function __construct(){
parent::__construct();
$this->is_team = isset($this->team);

// does some other stuff bellow
}

In this model I wanted to check if another model called "team" exists. But for some reason it returns me this error:

A PHP Error was encountered

Severity: Notice
Message: Undefined property: Dashboard::$team
Filename: core/Model.php
Line Number: 51

The error disappears if I remove the line completely, so I guess it can't be caused from somewhere else.

Any ideas on how to fix or replace this?

Thanks in advance.
