Enabling / Disabling alpha pager by arguments

5.x-1.4, Miscellaneous, feature request, normal, patch (code needs work)

Hi! I am using D5.7 with views & alpha pager 5.x-1.4.
I created a view to list all the nodes of my custom "people" content type.
And I am using alpha pager to group the view output sorting by second name.
The view provides a page, with teaser list, and I set the pager to alpha. My view URL is
/query/people/
The view also can take a NodeID as argument, and my arguments handling code set the view to type=node, if a nid is passed as arguments. By example:
/query/people/it/87
/query/people/en/87
if ($args[0] && is_numeric(arg(3))) {  $view->page_type = 'node';  $args[0] = arg(3);  $view->use_pager = FALSE;}if ($args[0] && !(arg(3))) { $args[0]='';}return $args;
My problem is that I DON'T want the pager, when showing a single node. How can I disable the aplha pager, in the arguments handling code? It seams that
$view->use_pager = FALSE;
does not work.
Can you hel me? Is it possible?
Thanks,
GP
