I add the action to work flow changes. From (creation) to submitted (I created this status). The action effect on a node. And i got the empty object. On Tue, Jul 13, 2010 at 9:46 PM, Vandyk, John K [ENT] <jvandyk@iastate.edu>wrote:

It looks like you are actually writing an action. In that case, the first parameter is populated by the native object that the action is working on. For example, if you are triggering an unpublish action when a node is edited, the object that you are working on is a node, and the trigger system will send the node object along to the action call as the first parameter.
The problem is that the first parameter is empty.
However, if you want to do something crazy like unpublish a node when a comment is submitted, you are acting on a comment object, not a node object.
My object is a node.
If you run an unpublish node action in that case, the trigger system will expend a little effort trying to make sure that the unpublish-a-node action (which works on nodes) gets a node. See
http://api.drupal.org/api/function/trigger_comment/6 http://api.drupal.org/api/function/_trigger_normalize_comment_context/6
Since some actions can be called in multiple contexts, you will see them doing gyrations like this:
http://api.drupal.org/api/function/system_message_action/6
The short answer is, ask yourself whether your action will ever be used in a weird context, and if you might have to pluck the $node from the $context or do a node_load() from some information in the context that could lead you to the node.

When i implement hook_action_info(), i found the first para *$node* is empty. My question is function mymodule_myaction_action(&$node, $context = array()) { $node = $context['node']; // should this line be added? ... } Or something else error? -- A decathlon Drupal developer & programmer http://blog.eood.cn/
