Strange - when I overwrote this protected method I got really strange results and my whole Admin interface was whacked.
Here is the excerpt from my php file
PHP Code:
namespace XLite\Module\KR\KRFeatures\View;
abstract class Countries extends \XLite\View\Tabs\ATabs implements \XLite\Base\IDecorator
{
protected function isCityMasksEditEnabled()
{
return true;
}
}
