Hello, In a module with its own node type, the node is not fully loaded when using preview. In hook_load(), I return my own extra fields to the node: return array('mynodetype' => $extra); In hook_view(), $node->mynodetype is set when viewing the node, but not when editing then previewing the same node. Isn't the node loaded as for a normal node view? I've searched drupal.org but didn't find anything terribly useful. I found this old forum post: Philosophy of 'Preview' http://drupal.org/node/126750 And this old core issue, which I had helped reviewing at the time, but which is supposed to be fixed (though it was not said how it was fixed): node previews broken by missing hook_submit http://drupal.org/node/104047 Is this a known issue? Blessings, Augustin.
