Can't get HTTP step to send POST data?

[Rogier]

I'm having difficulties with the HTTP step. No matter what I try, I can't get it to send any POST parameters.

I've attached a minimal example that does 2 Post requests to a test script, one with form parameters, one with raw post data.

The script it calls outputs all get and post params it receives. It does not report any POST params for either call.

Who's doing something wrong, me or the HTTP step?

(PS. I'm using VBP 7.7a, latest version)
