[fw-mvc] View and action helpers

I'm working on an application where users should be able to log in.

I have an action helper that does acl stuff so I can control access in
my actions by doing something like:

pulic function secretAction() {
if (!$this->_helper->acl->isAllowed('Admin')) {
// ...
}
}

The acl helper fetches info from the authenticated used (if any) from
Zend_Auth and so forth.

Now, in my views I would also like an acl helper that I can use to for
instance decide which links to show in the menu. Since I already have a
perfectly valid action helper that does everything I need I was
wondering if it was kosher to simply instantiate that helper in my view
helper.

class My_View_Helper_Acl extends Zend_View_Helper_Abstract {
protected $helper = null;

public function acl() {
if ($this->helper === null) {
$this->helper = new My_Controller_Helper_Acl();
}

return $this;
}

public function isAllowed($resource) {
return $this->helper->isAllowed($resource);
}
}

And in my views I can do:

<?php if ($this->acl()->isAllowed('Admin')): ?>
display link to admin page
<?php endif; ?>

Is this the way to do it or is there some other solution I could use?
