SugarCRM custom form validation with UnderscoreJS.rst

Steps to add custom form validation with UnderscoreJS:

• Step 1: Include underscoreJS and custom validation in your metadata (current example: custom/modules/Contacts/metadata/editviewdefs.php)
• Step 2: Use _.wrap function to add your custom validation before of after Sugar original check_form function which validates the form with Sugar rules (current example: custom/modules/Contacts/js/customValidation.js)
• Step 3: Make a Quick Repair & Rebuild :-)
