The property class does not exist on object<SilverStripe\User...odel\EditableFormField>. Since you implemented __get, maybe consider adding a @property annotation.

Since your code implements the magic getter _get, this function will be called for any read access on an undefined variable. You can add the @property annotation to your class or interface to document the existence of this variable.

<?php

/**
 * @property int $x
 * @property int $y
 * @property string $text
 */
class MyLabel
{
    private $properties;

    private $allowedProperties = array('x', 'y', 'text');

    public function __get($name)
    {
        if (isset($properties[$name]) && in_array($name, $this->allowedProperties)) {
            return $properties[$name];
        } else {
            return null;
        }
    }

    public function __set($name, $value)
    {
        if (in_array($name, $this->allowedProperties)) {
            $properties[$name] = $value;
        } else {
            throw new \LogicException("Property $name is not defined.");
        }
    }

}

If the property has read access only, you can use the @property-read annotation instead.

Of course, you may also just have mistyped another name, in which case you should fix the error.

See also the PhpDoc documentation for @property.
