Trouble with view_cell - Zeff - 05-05-2021

Hi folks,
I tried to use the view_cell() function in a view file, but I always get an error:

Code:
TypeError

Return value of CodeIgniter\View\Cell::render() must be of the type string, null returned

My view file is very simple, I just inserted a view_cell() in the default CI welcome_message.php:

Code:
<div class="heroe">

    <h1>Welcome to CodeIgniter <?= CodeIgniter\CodeIgniter::CI_VERSION ?></h1>

    <h2>The small framework with powerful features</h2>

</div>

</header>

<!-- CONTENT -->

<?=view_cell('\App\Controllers\TestController::bar')?>

<section>

    <h1>About this page</h1>

The TestController.php (which has no constructor!) has a simple method:

Code:
public function bar()

{

    echo 'BAR';

}

I use no params, so it's a very simple test but I keep on getting this error!

Many thanks for the golden tip! [Image: wink.png]

echo returns nothing.
Your method must return a string.

return 'BAR'; instead of echo 'BAR';

Hello iRedds,
Thanks so much for your hint, it worked by returning a string. I was so used to echo views from the previous tutorials I followed and I missed this perticular difference...
You made my day!
