Hi there,
please note that I am a Toolset and WPML contractor and I have performed an in-depth debug before posting this report.
Please escalate this report to the dev team.

I am trying to: use a custom field of type "checkbox"

Link to a page where the issue can be seen: not available

I expected to see: the value of the field as configured

Instead, I got: PHP Fatal error.

The error only occurs when displaying a post that has the checkbox field set to checked.

Here's the full stack trace:

Fatal error: Uncaught Error: Undefined class constant 'WPML_CHECKBOX_SELECTED' in /app/public/wp-content/plugins/types/application/models/field/part/option.php:139 
Stack trace: 
#0 /app/public/wp-content/plugins/types/application/models/field/abstract.php(219): Types_Field_Part_Option->get_value() 
#1 /app/public/wp-content/plugins/types/application/models/field/part/option.php(225): Types_Field_Abstract->get_value_filtered(Array, Object(Types_Field_Part_Option)) 
#2 /app/public/wp-content/plugins/types/application/models/field/type/checkbox/view/frontend.php(33): Types_Field_Part_Option->get_value_filtered(Array) 
#3 /app/public/wp-content/plugins/types/application/models/field/view.php(42): Types_Field_Type_Checkbox_View_Frontend->get_value() 
#4 /app/public/wp-content/plugins/types/application/models/field/service.php(137): Types_Field_View->render() 
#5 /app/public/wp-content/plugins/types/application/functions_public.php(58): Types_Field_Service->render_frontend(Object(Types_Field_Gateway_Wordpress_Post), Object(WP_Post), in /app/public/wp-content/plugins/types/application/models/field/part/option.php on line 139

The problem occurs also with WPML not installed, and despite the explicit reference to WPML, it's strictly related to Types source code, and not to WPML.

Fix: The bug is very trivial, the name of the constant looks wrong. It should be WPML_SUFFIX_CHECKBOX_SELECTED instead of WPML_CHECKBOX_SELECTED.
