Community Builder Conditional: how to show a field only if a user looks his own profile in Joomla?

CBConditional.php

/**
 * @param FieldTable|TabTable $object
 * @param string              $reason
 * @param int                 $userId
 * @param null|bool           $js
 * @param null|bool           $reset
 * @return bool|int
 */
private static function parseConditions( $object, $reason, $userId, &$js = null )
//Function code goes here....
//Leave all the code and find a part starting with this line:
case 'customusers':
    if ( $andCondition->getString( 'user_users', 'displayed' ) === 'viewer' ) {
      $fieldValue						=	Application::MyUser()->getUserId();
    } else {
      $fieldValue						=	(int) $userId;
    }

    $operator							=	$andCondition->getInt( 'operator_users', 12 );
    $delimiter							=	$andCondition->getString( 'delimiter_users' );

    if ( ! $delimiter ) {
      $delimiter						=	',';
    }

    //You will see a line, that you need to comment out:
    //$value								=	$cbUser->replaceUserVars( $andCondition->getString( 'field_users' ), true, false, array(), false );
    //Below is the new 4 lines of code that we need to add:
    $field_users                        =   $andCondition->getString( 'field_users' );
    if ($field_users === 'viewing_user')
        $field_users = Application::MyUser()->getUserId();
    $value								=	$cbUser->replaceUserVars( $field_users, true, false, array(), false );
    //End of new added lines, the original code continues below.
    break;

Not necessary. Just use [cb:userdata field="user_id" user="#me" /] to substitute in the viewing users id. That parameter supports substitutions.

Thank you so much! That's a perfect solution!
