node_load() during signup's node_save() breaks node data cached by CCK

Actually, the fix above does not work because signup executes after filefield_paths module, so the node_load() performed by signup module causes the node data to be cached by CCK after the fix above happens.

I'm moving this issue to the signup queue, as I have finally found a method to fix this in that module. I'm using 6.x-1.0-rc6 of signup module, and the following change to signup/includes/node_form.inc, function signup_save_node() fixed the issue here:

   $node = node_load($node->nid);
+  if (module_exists('content')) {
+    cache_clear_all('content:'. $node->nid .':'. $node->vid, content_cache_tablename());
+  }
   if (_signup_node_completed($node) && !empty($node->signup_status)) {

In the meantime, I'm using a custom module that I use for hacks, that has a weight higher than other modules, and here I'm implementing the following hook_nodeapi(), that also works:

/**
 * Implementation of hook_nodeapi().
 */
function MODULE_nodeapi(&$node, $op, $a3 = NULL, $a4 = NULL) {
  switch ($op) {
    case 'insert':
    case 'update':
      // Ensure content cache is cleared to account for changes in {file}
      // records when these have been updated by filefield_paths module
      // using tokens, broken by signup module doing a node_load() during
      // a node_save() operation.
      // See http ://drupal.org/node/605594
      cache_clear_all('content:'. $node->nid .':'. $node->vid, content_cache_tablename());
      break;
  }
}

Adjusting issue title.

@bibo: Nope, the static cache in node_load() does nothing here because the problem is CCK caches the node in its own cache table {cache_content}. We need to clear the entry created by CCK in that table for the node being processed here.
