No output with ng-repeat - angularjs

Question

i have a problem with this ng-repeat statement.
<div ng-repeat="m in mbct.messages track by $index" ng-click="mbct.message_click($index)" ng-class="mbct.set_class(m.gelesen)">
<div>ABS: <span ng-bind="m.abs"></span> </div>
<div>Betreff: <span ng-bind="m.betreff"></span> </div>
<div>Wann: <span ng-bind="m.timestamp"></span> </div>
<hr>
</div>
Controller:
var self = this;
self.messages = [];
self.massages_length = "";
//initialize variables when app starts
self.init = function(){
alert("Init-runs");
MessageService.get_messanges().then(
function(response){
self.messages = response.data;
self.messages_length = self.messages.length;
console.log(self.messages_length);
}
)
};
self.get_message_loop = $interval(function(){
MessageService.get_messanges().then(
function(response) {
if(self.messages_length < response.data.length){
console.log("new message");
self.messages = response.data;
self.messages_length = self.messages.length;
console.log("self.messages_length:" + self.messages_length);
}
else{
console.log("no new message");
}
}
);
},500);
And my Service:
gsgmain.factory('MessageService',['$http',function($http){
return{
get_messanges : function(){
var email = $("#php_username").html();
var data = {user_email: email, methode: "get_all_msg"};
var json_data = angular.toJson(data);
return $http.post("php/server.php", json_data);
},
send_message : function(abs,emp,message_text,betreff){
var data = {abs:abs, emp: emp, message: message_text,betreff:betreff,methode:"send_message"};
var json_data = angular.toJson(data);
return $http.post("php/server.php",json_data);
},
set_read: function(msg_id){
var data = {msg_id: msg_id,methode: "set_read"};
var json_data = angular.toJson(data);
return $http.post("php/server.php",json_data);
}
}
}]);
The ng-repeat-statement has no output, since i added the if-else-statement in "get_message_loop" to check if there are new messages.
Before the get_message_loop function looked like this:
self.get_message_loop = $interval(function(){
MessageService.get_messanges().then(
function(response) {
self.messages = response.data;
}
);
},500);
and erverything works fine.
Could you tell me why?
Thank you in advance.

Answer 1

me again :D,
I solved the Problem. I defined the controller twice. One time in the html-tag and the other time in my routeprovider. So the code did everything twice.
And always in the second run, the variable self.messages_length was undefined.
I removed one definition and now everything works fine ;)
