Problem using REST API through wavemaker

Hello,

I have a problem using the rest api with wavemaker. When I make a GET request with the RESTClientin FireFox everything is fine e.g:

get https://XXX.XXX.XXX.XXX:8281/vco/api/ the result is:

Status Code: 200 OK
Cache-Control: private
Content-Type: application/xhtml+xml;charset=UTF-8
Date: Sun, 06 Apr 2014 16:50:04 GMT
Expires: Thu, 01 Jan 1970 00:00:00 UTC
Server: Apache-Coyote/1.1
Transfer-Encoding: chunked

But when I try to connect to the same url using wavemaker I recive:  The response is not in a valid XML Format.

I use Orchestrator 5.5 and as far as i could see the token is not needed anymore in the header. Does anyone know why i keep getting this error?

Thanks!
