java - Spring RestController - jQuery PUT works only when changing certain values -
hello , thank in advanced:
i'm using spring 4 , jquery trying put data restcontroller. have 3 values passed controller: id, name, genre. reason, put request works every time change name field, if try update genre field, request never hits controller , fails 400: bad request.
i'm totally stumped. get, post, , delete methods working fine too. i'm going include config stuff since there's possibility may issue...
manage-artist.js (knockout , jquery):
... //update artist self.updateartist = function(artist){ self.clearmessages(); //put database $.ajax({ url: "../artist/" + artist.id(), method: "put", data: "id="+artist.id()+"&name="+artist.name()+"&genre="+artist.genre(), datatype: "json", success: function (data) { console.log("artist succesfully updated."); //update message self.successmessage("artist updated."); }, error: function (err) { console.log("an error occured while trying update artist."); //extract json response self.errorresponse(err.responsejson); //...more error handling } }); }; ... artistcontroller.java:

hard without seeing artist class, 400 bad request because of @valid annotation on artist in controller. validation checks if name not null, or params not null.
