JSON API create_post, always create double posts

Hi,

If I create a post using the create_post method, I always get double posts. I’m using a clean WordPress 3.5.1 install, this is what I do:

I create a nonce
http://myURL.com/app/get_nonce/?controller=posts&method=create_post

With the nonce I create a post with the title “Daves Test”
http://myURL.com/app/create_post/?nonce=nonce&title=Daves%20Test&status=publish

This gives me two posts with the same title, different ID and Permalink. I’d like to have just one post. Anyone knows a solution?

Thanks in advance,

Dave
