Default Value of Control

Hi,

We have a problem with the default value of control. Below is our code:

$this->add_control(
            'style'
            ,array(
                'label' 		=> 'Style'
                ,'type' 		=> Controls_Manager::SELECT
                ,'default' 		=> 'style-grid'
		,'options'		=> array(
			'style-grid' 			=> 'Grid'
			,'style-list' 			=> 'List'
			)		
                ,'description' 	=> ''
            )
        );
		
	$this->add_control(
            'img_bg'
            ,array(
                'label' 		=> 'Heading Background Image'
                ,'type' 		=> Controls_Manager::MEDIA
                ,'default' 		=> array( 'id' => '', 'url' => '' )		
                ,'description' 	=> ''
		,'condition'	=> array( 'style' => 'style-list' )
            )
        );

If we don’t select image for the Heading Background Image control. We set the Style control to Grid. The value of the $img_bg variable is NULL. The value of the $img_bg variable should be array( ‘id’ => ”, ‘url’ => ” ) (default).

This may cause error in som cases. When the control is not set, it should use the default value. Please fix this issue!

Thank you!
