How to make any view aware that the User Roles (ASP.NET MVC Identity) have changed in order to force any user to logout while he or she is browsing?

I think the question title is self-explanatory, maybe just a precision when I say while "he or she is browsing" I am thinking in terms of propagation or signal.
I don't want that he or she has to browse another place just to figure out that the Identity SecurityStamp has changed and has been signed out to be then redirected to the home page, I am already doing this but I am wondering if there a framework (I suspect most likely JS) that would make the operation a bit more "real-time".
[EDIT]
Probably a job for SignalR, I haven't tried this out, yet.

I managed to get a working solution with SignalR
First, pay attention to the order in which SignalR is setup in the Startup.Auth.cs How to send message via SignalR to a specific User(Identity Id)? and also create an implementation of the IUserIdProvider that is going to be registred only AFTER the Cookies and OwinContext in order to make it able to leverage the Identity User field (i.e. non-null).
public partial class Startup
{
public void ConfigureAuth(IAppBuilder appBuilder)
{
// Order matters here...
// Otherwise SignalR won't get Identity User information passed to Id Provider...
ConfigOwinContext(appBuilder);
ConfigCookies(appBuilder);
ConfigSignalR(appBuilder);
}
private static void ConfigOwinContext(IAppBuilder appBuilder)
{
appBuilder.CreatePerOwinContext(ApplicationDbContext.Create);
appBuilder.CreatePerOwinContext<ApplicationUserManager>(ApplicationUserManager.Create);
appBuilder.CreatePerOwinContext<ApplicationSignInManager>(ApplicationSignInManager.Create);
appBuilder.CreatePerOwinContext<ApplicationSignInManager>(ApplicationSignInManager.Create);
appBuilder.CreatePerOwinContext(LdapAdEmailAuthenticator.Create);
}
private static void ConfigCookies(IAppBuilder appBuilder)
{
appBuilder.UseCookieAuthentication(new CookieAuthenticationOptions
{
AuthenticationType = DefaultAuthenticationTypes.ApplicationCookie,
LoginPath = new PathString("/Account/Login"),
Provider = new CookieAuthenticationProvider
{
OnValidateIdentity = SecurityStampValidator.OnValidateIdentity<ApplicationUserManager, ApplicationUser>
(
TimeSpan.FromHours(4),
(manager, user) => user.GenerateUserIdentityAsync(manager)
)
}
});
appBuilder.UseExternalSignInCookie(DefaultAuthenticationTypes.ExternalCookie);
appBuilder.UseTwoFactorSignInCookie(DefaultAuthenticationTypes.TwoFactorCookie, TimeSpan.FromMinutes(5));
appBuilder.UseTwoFactorRememberBrowserCookie(DefaultAuthenticationTypes.TwoFactorRememberBrowserCookie);
}
private static void ConfigSignalR(IAppBuilder appBuilder)
{
appBuilder.MapSignalR();
var idProvider = new HubIdentityUserIdProvider();
GlobalHost.DependencyResolver.Register(typeof(IUserIdProvider), () => idProvider);
}
}
public class HubIdentityUserIdProvider : IUserIdProvider
{
public string GetUserId(IRequest request)
{
return request == null
? throw new ArgumentNullException(nameof(request))
: request.User?.Identity?.GetUserId();
}
}
Second, declare a hub on the server-side
public class UserHub : Hub
{
}
Third, in a controller (API or not) where a change that involves a logout of a specific user, force a signout + an update of the identity securitystamp:
var userHub = GlobalHost.ConnectionManager.GetHubContext<UserHub>();
userHub.Clients.User(userId).send("Roles added: " + rolesToAdd.Join() + Environment.NewLine + "Roles removed: " + rolesToRemove.Join());
return Request.CreateResponse(HttpStatusCode.OK);
Fourth, use the hub on the JS client-side, I created a partial view which is only used when the current user is authenticated, LoggedOutPartialView.cshtml:
#if (Request.IsAuthenticated)
{
<div class="modal fade" id="loggedOutModal" tabindex="-1" role="dialog" aria-labelledby="loggedOutModalLabel">
<div class="modal-dialog" role="document">
<div class="modal-content">
<div class="modal-header">
<h4 class="modal-title" id="loggedOutModalLabel">Notification</h4>
</div>
<div class="modal-body">
<h6 class="align-center">Sorry, but it seems that you just have been logged out!!!</h6>
</div>
<div class="modal-footer">
<button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
</div>
</div>
</div>
</div>
<script>
$(function() {
var userHub = $.connection.userHub;
console.log(userHub.client);
userHub.client.logout= function (message) {
$('#loggedOutModal').modal('show');
};
$.connection.hub.start().done(function () {
});
});
</script>
}

Salesforce Lightning Component will not update records via Apex call, freezes

Issue overview: Currently coding a Lightning Component to update records on a custom object. However, every time I trigger the update (via a ui:button), the page freezes and I don't see any errors in the debugger or console. Cannot for the life of me figure out why it won't work.
Context: The component has a number of dropdowns that are populated with records (with the label being the record name). Selecting a new value in the dropdown and hitting "Update" calls the below apex to change a custom field (Status__c = 'Ready') on the new selected item, and then updates the records that occur before it (Status__c = 'Complete). I do all of my security and update checks in another function during init, so you won't see that here (I can post the full code if needed). Just trying to get the update to work.
I would be eternally grateful if someone could show me the error of my ways :]. Always been a huge fan of stackoverflow and looking forward to contributing now that I finally signed up. Thanks for your time everyone!
Apex:
#AuraEnabled
public static void updateMilestones(String deployId,Boolean prodChanged,String newProdMile) {
if( prodChanged == true && newProdMile != null ) {
try {
decimal newProdStepNum;
List <Milestone__c> newReadyProdMile = New List<Milestone__c>();
for(Milestone__c mil1:[SELECT id, Status__c, Step_Order__c FROM Milestone__c
WHERE Deployment__c = :deployID
AND id = :newProdMile LIMIT 1]){
mil1.Status__c = 'Ready';
newProdStepNum = mil1.Step_Order__c;
newReadyProdMile.add(mil1);
}
List <Milestone__c> prodMilesComplete = New List<Milestone__c>();

I believe the issue is that you have fallen into the all too common trap of naming both a client side and a server side controller method the same (updateMilestones in this case). Try changing the name of either to make them unique and I expect that will get you running.
Yes, there is a bug on this and many of us have been making a very loud noise about getting it fixed!
Also we have a very active Salesforce specific Stack Exchange forum over here https://salesforce.stackexchange.com/ that will get more attention - especially if you tag your posts with lightning-components (e.g. I have my account configured to send me an email alert on every post tagged with lightning-components, locker-service, etc).

That might be javascript causing the error.As it's difficult to solve without knowing the error, I would suggest you debug the error.
Turn on debug mode.
a. From Setup, click Develop > Lightning Components.
b. Select the Enable Debug Mode checkbox.
c. Click Save.
In Chrome Developer Tools, check the "Pause on Caught Exceptions" checkbox in the Sources tab. This can often help finding the source of an issue. Other browsers may have similar options.
Add a debugger statement if you want to step through some code.
debugger;
This is useful when you have a rough idea where the problem might be happening.

Bootstrap modal won't close on click

I am very new to web dev. Still not too familiar with JavaScript. I am making an error message using that will load using code one of our dev guys created for a different page. I created modals that show on a click event and then close on a click event. For this one I am having the modal show based on returned URL parameters. And I am using code I copied from another page one of our dev guys made (not with Bootstrap modals).
The code below makes the modal show, but the buttons used to close the modal don't work. Not sure why.
This is the tag that will append the URL when returned:
(**...?companyName=ACME47 & err1=0 & err2=0 & err3=1**)
When the error values are 1 is loads the page to show the error modal with the text for that error in it.
Here is the code I'm using for the form (not attaching the style sheet, so it looks different).
jQuery(document).ready(function() {
// jQuery code snippet to get the dynamic variables stored in the url as parameters and store them as JavaScript variables ready for use with your scripts
$.urlParam = function(name) {
var results = new RegExp('[\?&]' + name + '=([^&#]*)').exec(window.location.href);
if (results == null) {
return null;
} else {
return results[1] || 0;
}
}
// Get url parameters
var err1 = new Number($.urlParam('err1'));
if (isNaN(err1)) {
err1 = new Number(0);
}
var err2 = new Number($.urlParam('err2'));
if (isNaN(err2)) {
err2 = new Number(0);
}
var err3 = new Number($.urlParam('err3'));
if (isNaN(err3)) {
err3 = new Number(0);
}
console.log('err1: ' + err1); // Writes a message to the browser console [f12]
console.log('err2: ' + err2); // Writes a message to the browser console [f12]
console.log('err3: ' + err3); // Writes a message to the browser console [f12]
console.log('CompanyName: ' + $.urlParam('companyName')); // Writes a message to the browser console [f12]
// Display error message function
// Read a page's GET URL variables and return them as an associative array.
if (err1 > 0) {
$("#error-box").show();
$("#error-1").show();
};
if (err2 > 0) {
$("#error-box").show();
$("#error-2").show();
};
if (err3 > 0) {
$("#error-box").show();
$("#error-3").show();
};
});
<div class="modal" id="error-box" style="display: none;" tabindex="-1" role="dialog" aria-labelledby="error-boxLabel">
<div class="modal-dialog" role="document" style="height:200px;">
<div class="modal-content" style="height: 100%;">
<div class="modal-header alert-danger">
<button type="button" class="close" data-dismiss="modal" aria-label="Close"><span aria-hidden="true">×</span>
</button>
<h4 class="modal-title text-danger">Form Submission Error</h4>
</div>
<div class="modal-body alert-danger" style="height: 100%;">
<div class="textWrapper">
<ul>
<li id="error-1" style="display: none;">That email address is already in use. (01)</li>
<li id="error-2" style="display: none;">A company with that name already has an account in this system. (02)</li>
<li id="error-3" style="display: none;">An unknown error has occurred. If your E-Mail or Phone Number was correctly filled in, you will be contacted shortly. (03)</li>
</ul>
</div>
</div>
<div class="modal-footer modal-footer-text">
<button type="button" class="btn btn-danger" data-dismiss="modal">Close</button>
</div>
</div>
</div>
</div>

You shouldn't be using jQuery's show() method to show the modal. Doing so doesn't register it with Bootstrap, so there's nothing to close with elements possessing the data-dismiss attribute. Use Bootstrap's method:
$("#error-box").modal('show');
Note that you may also need to use Bootstrap's show.bs.modal callback to show your error containers. It's possible that they won't be available to jQuery until the modal is initiated.

This is what I think you want see fiddle https://jsfiddle.net/sxh0n7d1/53/
Note: I set all the errors to visible in the fiddle, so that there is something to see how it works.
add this to your javascript
$('.close, .btn-danger').click(function() {
$( "#error-box" ).hide();
});

Set flash message after redirect in angularjs

I am just starting with Angular js. I have a doubt in that. I want to set flash messsage after redirect.
In my case, I have a form and am saving the data through http requst. In the success function I put window.location(). It is another page. I want to set a flash message in that page.
js
$scope.Save_Details = function (id)
{
$http.post(base_url+"sur/sur/save_data/"+id,{data:$scope.Surdata}).
success(function(response) {
// $scope.successTextAlert = "Saved";
// $scope.showSuccessAlert = true;
window.location = "#/surpage/nextpage?show_message= true";
});
}
new update
var messageFlag = $location.search().show_message;
if(messageFlag && messageFlag === 'true'){
alert(messageFlag);
$scope.successTextAlert = "Saved";
$scope.showSuccessAlertMsg = true;
}
view
<div class="alert alert-success" ng-show="showSuccessAlert">
<button type="button" class="close" data-ng-click="switchBool('showSuccessAlert')">×</button> <strong> {{successTextAlert}}</strong>
</div>
Anyone help me?

Put this code in HTML -
<!-- message text -->
<div class=" panel-{{alerts.class}}" ng-show="alerts.messages" >
<div ng-repeat="alert in alerts.messages track by $index" class="panel-body alert-{{alerts.class}}" >{{alert}}</div>
</div>
Put this code in angular model -
$rootScope.alert = function(type,msg){
$rootScope.message.push(msg);
$rootScope.alerts = {
class: type,
messages:$rootScope.message
}
}
For success message -
$rootScope.alert('success',"Success !!!");
For Error message -
$rootScope.alert('danger',"Error.");

You can use toastr JS specially for flash.
http://codeseven.github.io/toastr/demo.html
By using below js code, you can display a flash message.
For success message :
toastr"success";
For Error message :
toastr"success";

EDIT - Adding code
yourAppModule.controller('nextPageController', function($location){
var messageFlag = $location.search().show_message;
if(messageFlag && messageFlag === 'true'){
//show your message
}
});
When you navigate to "nextpage" pass a flag along -> #/surpage/nextpage?show_message= true
In the "nextpage" controller, read the query string value for
"show_message" ( inject $location to your controller and get value
using $location.search().show_message)
if that value == true, show your flash message

Twitter Bootstrap alert message closes without pressing close button

I have a problem with alert messages. I want to use the alert message as a warning to the user after a particular action has been performed. The issue I am facing is that the message shows and then closes on its own without user closing the message.
<div class="row-fluid">
<div class="alert span10 offset1" style="display: none" id="changeStatusMsg">
<a class="close" onclick="$('.alert').hide()" href="#">×</a>
<strong>Status has been changed.</strong>
</div>
I am using jquery to show the message -- $('#changeStatusMsg').show();
I used the solution mentioned here
But it does not help in my case.
function changeStatus(status, widgetExternalId){
$.ajax({
url : 'Controller',
data : { 'widget' : widgetExternalId,
'method' : (status == 'I' ? "activate" : "inactivate")
},
success : function(data) {
window.location = "myaccount.jsp";
$('#changeStatusMsg').show();
}
}
});
}

It is probably do to the fact you are not calling the action that is opening it. So the page is refreshing.
If you are doing it inline:
onclick="$('#changeStatusMsg').show();return false;"
If with a click event
$(".foobar").on("click",function (event) {
event.preventDefault();
$("#changeStatusMsg').show();
});
