How to display front end custom block to admin order view page

Question

I want to echo the following block to admin order view page.

echo $this->getLayout()->createBlock('compatibility/compatibilityblock')->setTemplate('tm/compatibility/savequote.phtml')->tohtml();

I have tried the following way but not worked.

echo $block = Mage::app()->getLayout()
->createBlock('compatibility/compatibilityblock')
->setData('area','frontend')
->setTemplate('tm/compatibility/savequote.phtml')->tohtml;

Answer 1

You need to set the area data from within the constructor of the block:

public function __construct()
{
    parent::__construct();
    $this->setData('area','frontend');
    $this->setTemplate('tm/compatibility/savequote.phtml');
}
