Change page template from module

[zaytseff]

Hi.

I make a simple soap module for contao 2.11
Module uses handlers for different events.
For some handlers i need change page temlate for display simle info in lightbox
So I would like to change the template layout
Next code does't work:

protected function service($handler)
{
    global $objPage;
    if ($handler == 'somehandler')
        $objPage->template = 'fe_page_service';
    ....
} 

Can i change page template from module or it impossible and i can find other ways?

P.S. Sorry about my english

Solved by change module logic without lightbox.
