It looks like wrap_parameters is not working right now in master for Katello controllers. Adam and I are stumped for the moment. Here's an example:
Started POST "//katello/api/organizations/ACME_Corporation/environments" for 127.0.0.1 at 2014-01-23 15:17:12 -0500
Processing by Katello::Api::V2::EnvironmentsController#create as JSON
Parameters: {"name"=>"test", "prior"=>"Library", "api_version"=>"v2", "organization_id"=>"ACME_Corporation"}
Setting locale: en
So v2 creates/updates probably won't work at the moment. If anyone has a clue, please let us know.
Thanks.
