[TYPO3-ect] lib smarty translation problem

[Marc Giffing]

Hello,

i am new here, i don't know there is someone interested, but i am 
missing a functionality in the file tx_lib_smarty.

The content key: '_content' must set to work with the translation:

function render($path) {
   $this->smarty->assign($this->getArrayCopy());
   $content = $this->smarty->display($this->_resolvePath($path));
   $this->set('_content', $content);
   return $content;
  }

return $content;

}

or?
