I'm having a bit of a problem getting a deferred returned from a method in a widget. The method is itself returns a Deferred as it's an xhrPost. The code is as such (using dojo 1.8)
Calling Code:
quorum = registry.byId("quorumPanel");
var deferredResponse = quorum.updateSelectionCount();
deferredResponse.then(function(data){
console.log("Success: ", data);
}, function(err){
console.log("Error: ", err);
});
and the code in the widget:
updateSelectionCount: function() {
var self = this;
var deferredResponse = xhr.post({
url: "ajxclwrp.php",
content: [arguments here],
handleAs: "json"});
deferredResponse.then(function(response) {
var anotherDeferred = new Deferred();
var _boolA = true;
var _boolB = true;
dojo.forEach(response.result, function(relationshipInfo){
[do a bunch of stuff here too set _boolA and/or _boolB]
});
self._sethasRequiredAttr(_hasRequired);
self._setHasRequestedAttr(_hasRequested);
self.quorumInfo.innerHTML = quorumHtml;
// Below is not working
anotherDeferred.resolve('foo');
return anotherDeferred;
});
}
Do I need to set up another promise and use promise/all. Im confused/frustrated at this point.
TIA.
the .then() method returns another deferred. You just need to put a return statement in.
updateSelectionCount: function() {
var self = this;
var deferredResponse = xhr.post({
url: "ajxclwrp.php",
content: [arguments here],
handleAs: "json"});
return deferredResponse.then(function(response) {
var _boolA = true;
var _boolB = true;
dojo.forEach(response.result, function(relationshipInfo){
[do a bunch of stuff here too set _boolA and/or _boolB]
});
self._sethasRequiredAttr(_hasRequired);
self._setHasRequestedAttr(_hasRequested);
self.quorumInfo.innerHTML = quorumHtml;
return "foo";
});
}

#wire(_getContacts,{recordId:'$recordId'}) wiredContacts({error,data}){
this.dataToRefresh = data;
if (data) {
this.contacts = this.dataToRefresh.recordList;
this.ContactsRecords = this.dataToRefresh.cList;
this.contactsSize = " Case Contacts (" + this.contacts.length + ")";
}else{
//
}
};
relateContacts() {
this.showSpinner = true;
this.showtable=false;
relateContacts({contacts: this.selected, recordId: this.recordId})
.then(data => {
this.showSpinner=false;
this.showtable=true;
this.showSuccessMessage();
refreshApex(this.dataToRefresh);
//location.reload();
this.isShowModal = false;
})
.catch(error => {
console.log(error);
this.showSpinner=false;
const evt = new ShowToastEvent({
title: 'Application Error',
message: error.body.message,
variant: 'error',
mode: 'sticky'
});
this.dispatchEvent(evt);
this.showSpinner = false;
});
}
For this code, I tried refreshApex with all possible ways. but I'm not sure the miss here. I've Checked all the blogs but everywhere, the solution is mentioned.
Tried refreshApex like below :
#wire(_getContacts,{recordId:'$recordId'}) wiredContacts({data}){
this.dataToRefresh = data;
But this also does not work
Ah that is a fun one ! Your issue is using destructuring in wiredContacts as the parameter.
(The {data} or {data,error} normally works as a parameter to the function being called back, except if you have to do refresh) Try this instead.
#wire(_getContacts,{recordId:'$recordId'}) wiredContacts(value){
this.dataToRefresh = value;
const {data, error} = value;
//Rest of you code now with data and error
}
Then in your other method you can do:
method(){
refreshApex(this.dataToRefresh);
}
Salesforce does show doing this in their example code, but it’s easy to miss and experience the fun you have been having with this.

I am trying to record every new session/user added to RTCMultiConnection.
i am using the following demo url in application
https://rtcmulticonnection.herokuapp.com/demos/Audio+Video+TextChat+FileSharing.html
Now i have added the following cdn reference to the code.
https://cdn.webrtc-experiment.com/RecordRTC.js
and this is the code i am working with but connection.streams[event.streamid].startRecording(); is not working.
// ..................RTCMultiConnection Code.............
// ......................................................
var connection = new RTCMultiConnection();
var btnStopRec = document.getElementById("btnStopRecording");
connection.socketURL = 'https://rtcmulticonnection.herokuapp.com:443/';
connection.enableFileSharing = true;
connection.session = {
audio: true,
video: true,
data: true,
};
connection.sdpConstraints.mandatory = {
OfferToReceiveAudio: true,
OfferToReceiveVideo: true,
};
connection.onstream = function (event)
{
document.body.appendChild(event.mediaElement);
console.log("stream recording starts")
connection.streams[event.streamid].startRecording();
console.log("stream recording started")
}
I included all possible situations in a single snippet, below. Please take only the code that you need:
// global object that contains multiple recorders
var recorders = {};
// auto start recorder as soon as stream starts/begins
connection.onstream = function(event) {
document.body.appendChild(event.mediaElement);
recorders[event.streamid] = RecordRTC(event.stream, {
type: 'video'
});
recorders[event.streamid].startRecording();
};
// auto stop recorder as soon as stream stops/ends
connection.onstreamended = function(event) {
if (recorders[event.streamid]) {
recorders[event.streamid].stopRecording(function() {
var blob = recorders[event.streamid].getBlob();
var url = URL.createObjectURL(blob);
window.open(url);
delete recorders[streamid]; // clear
});
}
if (event.mediaElement.parentNode) {
event.mediaElement.parentNode.removeChild(event.mediaElement);
}
};
// stop single recorder
document.getElementById('manually-stop-single-recording').onclick = function() {
var streamid = prompt('Enter streamid');
recorders[streamid].stopRecording(function() {
var blob = recorders[streamid].getBlob();
var url = URL.createObjectURL(blob);
window.open(url);
delete recorders[streamid]; // clear
});
};
// stop all recorders
document.getElementById('manually-stop-all-recordings').onclick = function() {
Object.keys(recorders).forEach(function(streamid) {
recorders[streamid].stopRecording(function() {
var blob = recorders[streamid].getBlob();
var url = URL.createObjectURL(blob);
window.open(url);
delete recorders[streamid]; // clear
});
});
};
// record outside onstream event
// i.e. start recording anytime manually
document.getElementById('record-stream-outside-the-onstream-event').onclick = function() {
var streamid = prompt('Enter streamid');
var stream = connection.streamEvents[streamid].stream;
recorders[streamid] = RecordRTC(stream, {
type: 'video'
});
recorders[streamid].startRecording();
};
I'm trying to work on knockout and unable to validate using knockout validation plugin.
[EDIT: update fiddle]
sample fiddle: jsfiddle.net/EHDD8
var CustVM = function () {
var self = this;
self.name = ko.observable().extend({ required: "Name is required" });
self.contact = ko.observable();
self.phone1 = ko.observable();
self.email = ko.observable().extend({email: true});
self.website = ko.observable().extend({required: "Website is required"});
self.Errors = ko.validation.group(self);
self.save = function () {
if (self.isValid()) {
alert("no error");
}
else {
alert("error");
}
alert("save clicked ");
};
self.cancel = function() {
alert("cancel clicked");
};
};
ko.applyBindings(new CustVM());
isValid is true even though i have not entered any required elements.
You are not using
ko.validation.registerExtenders();
that's why you are having problem, you can check my this ARticle:-

I am trying to use your api in a custom app with imported users.
Everything works fine (auth_token, login, call initiation) , but when the callee should get a response and add the remotestream nothing happens. no errors get shown in the console.
I would appreciate if someone takes a look at the code and tells me what i m missing.
I tried the vline demo at https://freeofcinema.vline.com and it worked with the same browsers and conditions between the two computers. In my app it is a http , but i tried it also with https, and the same problem came up. This is some simplified code i used to test the api.
var Streams = [];
var Vsession = null;
var Vline = (function(){
var Client;
var authToken;
var service_id = 'freeofcinema';
var profile = null;
var Person;
var Calls = [];
var onMessage = function(event){
//alert('message');
var msg = event.message, sender = msg.getSender();
console.log(sender.getDisplayName() +'sais: '+ msg.getBody());
console.log(event);
}
var onMediaSession = function(event){
console.log(event);
var mediaSession = event.target;
InitSession(mediaSession);
}
function Call(mediaSession) {
mediaSession.
on('change', alert_info);
}
function alert_info(b){
console.log(b);
}
function InitSession(mediaSession){
mediaSession.on('mediaSession:addRemoteStream', function(event) {
alert('addRemoteStream');
});
mediaSession.on('mediaSession:addLocalStream', function(event) {
alert('addLocalStream');
});
mediaSession.on('mediaSession:removeLocalStream mediaSession:removeRemoteStream', function(event) {
console.log('removedStream');
});
Calls.push(new Call(mediaSession));
}
return {
init : function(){
if(profile){
return;
}
profile = {
"displayName" : //some getusrname function...
};
$.post('vtoken.php',{//get auth token
id : Comm.Voip_user().id
},function(data){
authToken = data;
Client = vline.Client.create({
"serviceId": service_id,
"ui" : true
});
Client.on('recv:im', onMessage , this);
Client.on('add:mediaSession', onMediaSession, this);
Client.on('login', function(e) {
Vsession = e.target;
//alert('loged in');
});
Client.login(service_id, profile, authToken);
});
},
getPerson : function(id){//id of user to call
if(Vsession){
Vsession.getPerson(id).
done(function(person){
Person = person;
Vsession.startMedia(id);
});
}
}
}
}());
Thank you for your response.
I tried with one user from the app, and another from the https://freeofcinema.vline.com, and the same problem occured. Also the call (in pending state) gets terminated after a short while..
When passing ui:true when creating the client, you do not have to handle the media sessions yourself. Just comment the line Client.on('add:mediaSession', onMediaSession, this); and it should just work.
I have a fairly simple controller that gets a simple json list of objects ...
function ProductGroupsCtrl($scope, $http, $routeParams, sharedService, popupService) {
$scope.list = null;
$scope.selectedItem = null;
$scope.selectedItemJsonString = '';
$scope.selectItem = function (item) {
$scope.selectedItem = item;
$scope.selectedItemJsonString = JSON.stringify(item);
//alert(JSON.stringify(item));
};
$scope.closePopup = function () {
$scope.selectedItem = null;
$scope.selectedItemJsonString = '';
};
// sharedService.prepForBroadcast($routeParams.anotherVar);
$http({
method: 'GET',
url: '/ProductGroup'
}).success(function (data) {
$scope.list = data;
}).
error(function (data) {
$scope.message = 'There was an error with the data request.';
});
}
I then try to mock the request in the test class:
var scope, ctrl, $httpBackend, sharedServiceMock = {}, popupServiceMock = {};
beforeEach(inject(function (_$httpBackend_, $rootScope, $controller) {
$httpBackend = _$httpBackend_;
$httsypBackend.expectGET('/ProductGroup').
respond([{
ProductGroupID: 5,
MenuTitle: "Promotional Products",
AlternativeText: "Coming soon - a collection of environmentally friendly Promotional Products",
OrdinalPosition: 5,
Active: false
}]);
scope = $rootScope.$new();
ctrl = $controller(ProductGroupsCtrl, {
$scope: scope,
$http: $httpBackend,
sharedService: sharedServiceMock,
popupService: popupServiceMock
});}));
However I receive an error in the testacular window object undefined. What have I done wrong here?
Found the answer. If I remove the error callback function from the $http.get method then it works, i.e. remove the following ...
error(function (data) {
$scope.message = 'There was an error with the data request.';
}
I have to say Angular sure is a steep learning curve for someone who is not a day to day JavaScript programmer (although I seem to be doing more and more). Thanks for the help anyway KatieK :-)
