Dependency for all fields readonly based on a fields value ( checkbox) ?

Working with Professional, Version 9.0.0
I`m new into SugarCRM, I have a little question. 
The case is: I Make fields read-only ( most ) but not only one ( the checkbox) in module Quote.
When I click the checkbox all fields must be read-only and when I uncheck the fields be must editable.

I write a dependency looks like : 

$allFields = $GLOBALS['dictionary']['Quote']['fields'];

foreach ($allFields as $field => $val) {

    if($field == 'approved_c'){

        continue;

    }

    $dependencies['Quotes']['readonly_' . $field . '_dep'] = array(

        'hooks' => array('all'),

        'trigger' => 'true',

        'triggerFields' => array('approved_c'),

        'onload' => true,

        'actions' => array(

            array(

                'name' => 'ReadOnly',

                'params' => array(

                    'target' => $field,

                    'label' => $field . '_label',

                    'value'  => 'equal($approved_c, 1)',

                ),

            ),

        ),

    );

}

approved_c is my checkbox. 

So it works but not correct because when I uncheck the field and click save I have an error in the browser console : 

Uncaught TypeError: Cannot read property 'setValue' 

And my DateTime fields look like:

Any suggestions?
