according to the documentation of angular http API "error" method is called when server response status is 400 and above.
does this mean that when ever I want to check for status codes of 202, 204 ... to 400 I need to check them with If( status = 202 ) , if (status 204) ...
isn't there something like onViolationContrains like in GWT RPC, and RequestFactory ?, if not, how do you this.
