Publication form url was http instead of https causing requests to be redirected and resent as GET not POST requests. This prevented publication of metadata records.
The important changes are in templates/html/publication.html.tpl where the form action url has been changed to generate a relative url. The rest of the java code changes are just removing the UriComponentsBuilder that is not needed in the TransitionResource as a url is not being stored in this resource (it has been created in the publication template).
