Empty outputs on deployment services

Hi.

I had a problem, when I updated Deploy module on 7.x-2.0-alpha3 version.
When I want to call most of deployment service method by services API (XML-RPC server), empty string returned.

Seems, that services callbacks needs to be changed - look at my patch of sites/all/modules/deploy/modules/deploy_services/deploy_services.services.inc file, where callbacks are defined.
Than deploy services calls returning expecting results.

Thanks.
