XML-RPC

Hi, I’m trying to use the XML-RPC method wp.newComment.

The arguments I supply are
blogId
username
password
postId
struct(containing:)
-content
-author
-author_url
-author_email
-comment_parent
*content is the only thing that is in the struct every time I try to post a new comment. The others i’ve tried varying if I can leave them out or include them, but it hasn’t changed the behavior.

Here’s the problem: Whenever I post to a new comment, I can see the comment and the time and date of when I posted it, but I can’t see the content in the comment. If I ever try to post a comment on the same thread, an XHTML page is returned that gives “Duplicate comment detected” error, whether or not I’ve changed the content in the comment.
