Hi Folks,

I defined a call to hook_menu and I created a path "modc/ajax/%node" (see below) with the attendant callback, "modc_ajax_node($node)".  I am requesting the menu entry from a view by rewriting a title field as a link: "modc/ajax/[nid]".

So far, so good.  All the plumbing works, for the most part.

First mystery: In my callback function, modc_ajax_node($node), I expected $node to be an integer because I think I told the view to use that replacement pattern, [nid], however var_dump($node) reveals it to be a fully developed structure that, with my level of experience, I can't distinguish from the internal representation of a node, and in fact it appears to be the correct node, guessing by what I see in the fields.

Second mystery: O.K., so let's suppose that I have an internally represented node, and I want to display it. Shouldn't: return render($node): produce a display of the page?  ... because it doesn't.   So, I expect I am calling the wrong thing.  Can anybody tell me how I convert the internal representation of a node to the printable HTML that I need?  P.S.:  If my modc_ajax_node($node) callback executes: return "<P>Hi!</P>"; then I see a fully rendered page showing the title, 'Module C AJAX node callback', with content "Hi!", just as expected. 

Chris.

    $items['modc/ajax/%node'] = array (
        'title' => 'Module C AJAX node callback',
        'page callback' => 'modc_ajax_node',
        'page arguments' => array(2),
        'access arguments' => array('access content'),
        'type' => MENU_CALLBACK,
        );
