I have a CheckboxSetField in my form and would like to send those data in an email when the form is submitted. However, I am getting the following errors:

FATAL ERROR: ArrayData::__construct: Parameter needs to be an object or associative array
At line 39 in C:\Program Files\wamp\www\web\sapphire\core\ArrayData.php

and

FATAL ERROR: Object::__call() Method 'forTemplate' not found in class ''
At line 199 in C:\Program Files\wamp\www\web\sapphire\core\Object.php

user_error(Object::__call() Method 'forTemplate' not found in class '',256)
line 199 of Object.php

Object->__call(forTemplate,Array)

ArrayData->forTemplate()
line 420 of ViewableData.php

When I added forTemplate to the ArrayData.php, the second error was gone.

I use this code to populate template of the email:

$email->populateTemplate(array(
'FirstName' => $data['FirstName'],
'LastName' => $data['LastName'],
'Title' => $data['Title'],
'Company' => $data['Company'],
'Reason' => $data['Reason'],
'Email' => $data['Email'],
'Phone' => $data['Phone']
));

where Reason is an array data of the CheckboxSetField in my form.

Thanks.
