Description
I created a simple rule that assigns a certain menu item for a content type. As soon as that is done I don't have a $node object anymore when I access it in my page.tpl.php. When I delete the rule or deactivate node_breadcrumbs everything works as intended. Am I missing something or is this a bug?
#1
Drupal does not set $node variable in page.tpl.php. Do you set it in template.php? Show your code where you init it.

It doesn't? Ok, then I have a fundamental understanding problem. I never initialize $node, I just use it. But I also checked and I cannot access $node directly in the page.tpl.php.
I should clarify. I have a custom theme, in the page.tpl.php I call a function that renders some links for the current node based on the users permission
<?php print dart_render_operations($node) ?>In my template.php file the actual function is
function dart_render_operations ($node) {
$menu_item = menu_get_item();
$active_path = $menu_item["href"];
$output = "";
if (node_access("create", $node->type)) {
...
}
if (node_access("update", $node)) {
...
}
if (node_access("delete", $node)) {
...
}
return $output;
}
This way the $node variable is set correctly and I can access it. However, I never initialized it knowingly. I've seen this usage in some default theme and just assumed that it is there (and it worked curiously).
But as you said I cannot access $node from the page.tpl.php. So I'm assuming it is injected from Drupal's template mechanism somewhere when the template is parsed?
Anyway, using this construction everything works when I don't have a rule defined for node_breadcrumb. As soon as I define a rule for a content type the above routines don't work anymore.

http://drupal.org/node/572718 - similar issue
Add this code to dart_render_operations as first line:
if (!$node && arg(0) == 'node' && is_numeric($nid = arg(1))) $node = node_load($nid);
PS: Here vars for page.tpl.php http://api.drupal.org/api/drupal/modules--system--page.tpl.php and there are no $node var.
