Can I do a permission check in PreDispatch?

[Jaxel]

I have a public controller... each function of it, has their own little permissions. But there is also a global permission which must be true in order to do any of the functions. Do I need to check this global permission in every single function? Or can I do it in a preDispatch? I am trying using the following code below, but it doesn't seem to fire. If I move this permission check into each function, it works, but I would rather keep the redundancy down.

public function _preDispatch($action)
{
	parent::_preDispatch($action);

	$this->perms = $this->getModelFromCache('EWRmedio_Model_Perms')->getPerm();

	if (!$this->perms['view']) { return $this->responseNoPermission(); } // ???
}

You can do that, but you can't return from that function - you need to throw an exception:

throw $this->responseException($this->responseNoPermission());

For example, though there's actually a method that combines those 2 calls...

yep
throw $this->getNoPermissionResponseException()

Thanks, this was exactly what I was looking for.
