why is the node id missing from the comment:edit action? When I setup a trigger on comment creation and edit that fires the action "send email" I have the folling tags available in the action editor that seem to be missing the nid on output:

[comment:edit-url]
[comment:url]
[comment:url:absolute]


This gives me the following output in emails

http://example.com/comment//edit
http://example.com/comment/#comment-
http://example.com/comment/#comment-


Is this a flaw in the D7 or and I not doing it right?

Thanks in advance for any insights.
@Denford: You are right in saying that comments do have ids. They are just called cids and not nids :-)

What is the trigger that you are firing? My guess is that for a new comment posted, you are not seeing the 'cids' because they would be available only to the trigger 'after saving a new comment' and not the trigger 'when either saving a new comment or updating.. blah blah'.
