At the end of the day, what Apache Isis needs is an HTTP POST here, with the JSON as the body and not in the URL.
What Stef noticed (and I hadn't, I admit) was that in your example you had a URL that was: POST http://localhost:8080/restful/services/domainapp.dom.BusinessEntities.AuditItemMenu/actions/create/invoke?asset=%7B%22href%22:%22http:%2F%2Flocalhost:8080%2Frestful%2Fobjects%2Fbusinessentities.Asset%2F36%22%7D&audit=%7B%22href%22:%22http:%2F%2Flocalhost:8080%2Frestful%2Fobjects%2Fbusinessentities.Audit%2F2%22%7D&location=%7B%22href%22:%22http:%2F%2Flocalhost:8080%2Frestful%2Fobjects%2Fbusinessentities.Location%2F47%22%7D So, you can see that the long URL encoded bit after invoke?=asset=... is the json data being included in the URL. Stef suggested using $http.post(" http://localhost:8080/restful/services/domainapp.dom.BusinessEntities.AuditItemMenu/actions/create/invoke ", data) where the second argument to that method is (I presume) going to be made into the body of the HTTP POST, rather than the URL. In using AuditItemCreate.save(data) - which is Angular's abstraction on top of HTTP - I presume it equates to the same thing.
