can't create or delete folders and object

[ruyarce]

Hi,
I'm having troubles trying to create or delete folders and objects with Nuxeo.
The get methos works fine, but i can't use the create, update or delete methods
the server throws me this message:
"...status: 405,
exception: 'notSupported',
message: 'Unknown action'..."
But the getAllowableActions method throws me that i can do this things
