[Closed] "Creating default object from empty value in..."

I have added a wrapper to one of my Joomla pages, but I see this error on the page after it loads:

Warning: Creating default object from empty value in C:\xampp\htdocs\joomla\components\com_joomdle\views\wrapper\view.html.php on line 27

Any ideas on how to fix it?

It is a warning: you could disable showing warning in your php config.

Also, I think you could fix the code by adding first:
$this->wrapper = new stdClass();

Adding "$this->wrapper = new stdClass();" to the PHP file worked like a charm. Thank you.
