Replacing SignalR callbacks doesn't work -

update: simplified error case further , filed issue on signalr's github page. can see issue here: https://github.com/signalr/signalr/issues/1828. bug has nothing angularjs.

i have project uses asp.net , signalr on backend , angularjs frontend. works fine except when move within angularjs , controllers created again, cannot replace original signalr callback methods.

here code controller:

function signalrproblemctrl($scope) {     var bar = $.connection.bar;     $.connection.hub.start();      $scope.currentmessage = "";      $scope.messages = [];     $scope.messages.push("hello!");      var date = new date();     bar.client.addmessage = function (message) {         $scope.$apply(function () {             console.log("callback set on " + date + ": " + message);             $scope.messages.push(message);         });     };      $scope.send = function () {         bar.server.send($scope.currentmessage, "extra data");     };  } signalrproblemctrl.$inject = ['$scope']; 

on first visit controller can send , receive messages , angular bindings work fine. console has output:

callback set on fri apr 05 2013 14:37:13 gmt+0300 (e. europe daylight time): first page load controllers.js:37 

this , dandy. problem arises after moving page , vising signalrproblemctrl again. time can send , receive messages, message gets written console bindings not updated. output in console points root cause:

callback set on fri apr 05 2013 14:37:13 gmt+0300 (e. europe daylight time): second page load controllers.js:37 

so bindings don't updated because on second creation of controller first callback doesn't replaced. signalr messages still go first callback has $scope of previous instance of controller , view doesn't updated latest messages.

why this? why signalr hold on first callback?

ps. tried replacing callback immediately. code latest callback (one date2) used correctly.

var date = new date(); bar.client.addmessage = function (message) {     $scope.$apply(function () {         console.log("callback set on " + date + ": " + message);         $scope.messages.push(message);     }); };  var date2 = new date(); bar.client.addmessage = function (message) {     $scope.$apply(function () {         console.log("callback set on " + date2 + ": " + message);         $scope.messages.push(message);     }); }; 

after filing issue on github (https://github.com/signalr/signalr/issues/1828) got comment how solve this.

you can check out solution at: signalr (1.0.0-alpha2) hubs - can add client functions after connection has been started?
