I have integrated One Third Party Reporting API with Citrus, Have implemented the TestListener interface. I am observing One Test Case is Printed Twice in the Reporting Dash Board, The Moment i debug i see the Reporting method is executed twice.
#Override
public void onTestSuccess(TestCase test) {
ETest.log(LogStatus.PASS, "Test Case Passed"); (--> This line Executed twice every time
}
Can you guys help me here.

As of Build 8201.2025 there has been an unexpected change to the order of events when loading a VSTO addin with a Ribbon in Word.
Using Office version 16.0.8067.2115 or older. When loading the addin the following order of events is observed (as has always been the case).
Ribbon_Load event
ThisAddin_Startup event
Using Office versions 8201.2025, 8201.2064 or 8201.2075 or newer the order of events is reversed which is an unexpected breaking change.
ThisAddin_Startup event
Ribbon_Load event
I have created a simple VSTO Addin using a Visual Designer Ribbon to demonstrate the issue.
>
Public Class Ribbon1
Private Sub Ribbon1_Load(ByVal sender As System.Object, ByVal e As RibbonUIEventArgs) Handles MyBase.Load
System.Diagnostics.Debug.Write("Ribbon1_Load event called.")
'Pass the Ribbon to the Addin.
ThisAddIn.MyRibbon = Me
End Sub
End Class
Public Class ThisAddIn
Public Shared Property MyRibbon As Ribbon1 = Nothing
Private Sub ThisAddIn_Startup() Handles Me.Startup
Debug.Write("ThisAddin_Startup Called")
If (MyRibbon Is Nothing) Then
Debug.Write("MyRibbon is nothing - the ribbon was not captured.")
Else
Debug.Write("Ribbon captured successfully.")
End If
End Sub
End Class

I have posted this up on the Microsoft Support forums however they have stopped responding and since released this version to the Current office channel I need help from the dev community.
Has anyone found a successful workaround? This change of timing is causing alot of problems with how we initialise. It would be ideal for Microsoft Support to provide a solution or workaround until they investigate this bug.
I always got Ribbon_Load before ThisAddin_Startup because I use Ribbon XML. Ribbon UI allow less controls ... As the both are "entry" points, I suggest you to use only Ribbon1_Load at startup. Or, if you use the Ribbon XML model and you want the very very first entry point, try its constructor
I am not feeling that issue as a bug, to make Word fast many processes are asynchronous. So, in my opinion, the first of ThisAddin_Startup or Ribbon1_Load to start can accidentally change depending on many factors: System performances, Word started alone, Word started via a doc ...
Hope this helps someone! We used the following workaround successfully to work around the changed office load behavior.
Within ThisAddIn_Startup loop until the Ribbon load event has fired and the ribbon is captured.

Am new to Microservices and CQRS event handling. I am trying to understand with one simple task. In this task I have three REST external services to handle one transaction/request(Service). The three services are
step1: customer create.
step2: create business for customer
step3: Create Address for business.
I want to implement SAGA for these events with InMemorySagaRepository and saga manager.
Where exactly I have to initiate the SagaManager with repository, Is it in RestController or in CommandHandler ?
Can you please help me in understanding sagas flow ?
Thanks in Advance.
Half a year later, and I'm making an edit as I've now taken a course held by Greg Young called Greg Young's CQRS, Domain Events, Event Sourcing and how to apply DDD
I really recommend it to anyone thinking about CQRS. Help A LOT to understand what things actually are
Original anwser
In our product we use Sagas as something that reacts to events.
This means that our sagas are really just Subscribers to a specific Event. The saga then holds some logic as to whether it should do something or not.
If the saga finds that an action should be taken, it creates a Command which it puts on the CommandBus.
This means that Sagas are just 'reactors' and use the same path in as a user would (skipping the APIs etc).
But what a Saga really is, and what it should do, differs from the one talking about them to the other. (Disclaimer: This is how I read these posts, they might actually all say the same thing, but in a way to fluffy way for me [+my team] to see that)
http://blog.jonathanoliver.com/cqrs-sagas-with-event-sourcing-part-i-of-ii/ for example, raises the point that Sagas should not contain 'business logic' (anything that contains 'if' is business logic according to the post).
https://msdn.microsoft.com/en-us/library/jj591569.aspx Talks about Sagas as 'Process managers' which coordinate things between different Aggregates (remember that Aggregate1 can't talk to Aggregat2 directly, so a 'Process manager' is required to orchestrate the communication). To put it simply: Event -> Saga -> Command -> Event -> Saga... To reach the final destination.
https://lostechies.com/jimmybogard/2013/03/21/saga-implementation-patterns-variations/ Talks about two different patterns of what a Saga is. One is 'Publish-gatherer' which basically coordinates what should happen based on a Command. The other is 'Reporter', which just reports the status of things to where they need to go. It doesn't coordinate things, it just reports whatever it needs to report.
http://kellabyte.com/2012/05/30/clarifying-the-saga-pattern/ Has a write-up of what the Saga-pattern 'is'. The claim is that Sagas should/could compensate for different workflows that break.
http://cqrs.nu/Faq/sagas Has a very short description on what Sagas are and basically says 'They are state machines that lets aggregates react to other aggregates'.
So, given that, what is it you actually want the Saga to do? Should it coordinate everything? Or should it just react and not care what the Aggregates do?
My edited part
So, after taking the course on CQRS and talking with Greg about this, I've come to the conclusion that there is quite a lot of confusion out there on the web.
Lets start with just the concept 'Saga'. A Saga has actually nothing to do with CQRS. It's not a concept of it. 'Saga' a form of a two-phase-commit, only it's optimised for success rather than fail ( https://en.wikipedia.org/wiki/Compensating_transaction )
Now, what most people mean when they talk CQRS and say "Saga" is "Process Manager". And process managers are quite complicated it seems (Greg has a whole other course for just Process Managers).
Basically what they do is the manage the whole process of something (as the name suggests). The link to Microsoft is pretty much what it's all about.
To answer the question:
Where exactly I have to initiate the SagaManager with repository, Is it in RestController or in CommandHandler ?
Outside of them both. A Process Manager is it's own thing. It spans aggregates and repositories. Conceptually it might be better to look at it as a user doing all the things you want the PM do to, just that you program the users interaction and tell it what to listen for.
Disclaimer: I do not work for Greg, or anyone that stands to gain on my promotion for taking his courses. It's just that I learned a lot from it, so I recommend it just like I would recommend reading Eric Evans book on DDD.
In my application i've build Saga process manager using this MSDN documentation, my Saga is implemented in Application Service layer, it listens Events of Sales, Warehouse & Billing bounded contexts and on event occurrence sends Commands via Service Bus.
Simple example, hope it helps you to analyze how to build your saga (I am registering saga as handler in Composition Root) ;):
SAGA:
public class SalesSaga : Saga<SalesSagaData>,
ISagaStartedBy<OrderPlaced>,
IMessageHandler<StockReserved>,
IMessageHandler<PaymentAccepted>
{
private readonly ISagaPersister storage;
private readonly IBus bus;
public SalesSaga(ISagaPersister storage, IBus bus)
{
this.storage = storage;
this.bus = bus;
}
public void Handle(OrderPlaced message)
{
// Send ReserveStock command
// Save SalesSagaData
}
public void Handle(StockReserved message)
{
// Restore & Update SalesSagaData
// Send BillCustomer command
// Save SalesSagaData
}
public void Handle(PaymentAccepted message)
{
// Restore & Update SalesSagaData
// Send AcceptOrder command
// Complete Saga (Dispose SalesSagaData)
}
}
InMemorySagaPersister: (as SalesSagaDataID i am using OrderID its unique across whole process)
public sealed class InMemorySagaPersister : ISagaPersister
{
private static readonly Lazy<InMemorySagaPersister> instance = new Lazy<InMemorySagaPersister>(() => new InMemorySagaPersister());
private InMemorySagaPersister()
{
}
public static InMemorySagaPersister Instance
{
get
{
return instance.Value;
}
}
ConcurrentDictionary<int, ISagaData> data = new ConcurrentDictionary<int, ISagaData>();
public T GetByID<T>(int id) where T : ISagaData
{
T value;
var tData = new ConcurrentDictionary<int, T>(data.Where(c => c.Value.GetType() == typeof(T))
.Select(c => new KeyValuePair<int, T>(c.Key, (T)c.Value))
.ToArray());
tData.TryGetValue(id, out value);
return value;
}
public bool Save(ISagaData sagaData)
{
bool result;
ISagaData existingValue;
data.TryGetValue(sagaData.Id, out existingValue);
if (existingValue == null)
result = data.TryAdd(sagaData.Id, sagaData);
else
result = data.TryUpdate(sagaData.Id, sagaData, existingValue);
return result;
}
public bool Complete(ISagaData sagaData)
{
ISagaData existingValue;
return data.TryRemove(sagaData.Id, out existingValue);
}
}
One approach might be to have some sort of starting command that starts the Saga. In this scenario it would be configured in your composition root to listen to a certain command type. Once a command has been received in your message dispatcher (or whatever middleware messaging stuff you have) it would look for any Sagas that have been registered to be started by the command. You would then create the Saga and pass it the command. It could then react to other commands and events as they happen.
In your scenario I would suggest your Saga is a type of command handler so the initiation of it would be upon receiving a command
I'm having a rare issue in my code, I have a method that makes a very simple validation based on a string variable:
private void showNextStep(String psCondition,String poStepName){
int liCurrentStep=Integer.valueOf(poStepName);
String lsNextTrueStep=moSteps[liCurrentStep][4];
String liNextFalseStep=moSteps[liCurrentStep][5];
if ("Yes".equals(psCondition)){
moFrmStepsContainer.getField(liNextFalseStep).hide();
moFrmStepsContainer.getField(lsNextTrueStep).show();
}else{
moFrmStepsContainer.getField(liNextFalseStep).show();
moFrmStepsContainer.getField(lsNextTrueStep).hide();
}
}
Now, here is the ticky part: if I execute the application without debugging mode, it does the validation right all the time, how ever if don't it always goes to the else block (or at least I think) I tried to use JS alerts (I have a class that calls JS methods) to debug manually and check the valors of the variables; the valors where all right and the validation was also good. This means that only debugging or putting alerts before at the beggining of the IF block it does the validation right, otherwise it always goes to the ELSE, what do you think it could be?
It might be worth mentioning this is a web application made in netbeans 6.9, using the framework GWT 2.1. This application runs in firefox 25.0.1
Thank you!
UPDATE
Here is the code of the event that calls my method
final ComboBoxItem loYesNo=new ComboBoxItem("cmbYesNo" + moSteps[liStepIndex][0],"");
loYesNo.setValueMap("Yes","No");
loYesNo.setVisible(false);
loYesNo.setAttribute("parent", liStepIndex);
loYesNo.addChangedHandler(new ChangedHandler() {
public void onChanged(ChangedEvent poEvent){
String lsStepName=loYesNo.getName();
FormItem loItem=moFrmStepsContainer.getField(lsStepName);
String liStepNumber=String.valueOf(loItem.getAttributeAsInt("parent"));
showNextStep((String)poEvent.getItem().getValue(),liStepNumber);
}
});
I have the following architecture at the moment:
Load(Play app with basic interface for load tests) -> Gateway(Spray application with REST interface for incoming messages) -> Processor(akka app that works with MongoDB) -> MongoDB
Everything works fine as long as number of messages I am pushing through is low. However when I try to push 10000 events, that will eventully end up at MongoDB as documents, it stops at random places, for example on 742 message or 982 message and does nothing after.
What would be the best way to debug such situations? On the load side I am just pushing hard into the REST service:
for (i ← 0 until users) workerRouter ! Load(server, i)
and then in the workerRouter
WS.url(server + "/track/message").post(Json.toJson(newUser)).map { response =>
println(response.body)
true
}
On the spray side:
pathPrefix("track") {
path("message") {
post {
entity(as[TrackObj]) { msg =>
processors ! msg
complete("")
}
}
}
}
On the processor side it's just basically an insert into a collection. Any suggestions on where to start from?
Update:
I tried to move the logic of creating messages to the Gatewat, did a cycle of 1 to 10000 and it works just fine. However if spray and play are involed in a pipeline it interrupts and random places. Any suggestions on how to debug in this case?
In a distributed and parallel environment it is next to impossible to create a system that work reliably. Whatever debugging method you use it will only allow you to find a few bugs that will happen during the debug session.
Once our team spent 3 months(!) while tuning an application for a robust 24/7 working. And still there were bugs. Then we applied a method of Model checking (Spin). Within a couple of weeks we implemented a model that allowed us to get a robust application. However, model checking requires a bit different way of thinking and it can be difficult to start.
I moved the load test app to Spray framework and now it works like a charm. So I suppose the problem was somewhere in the way that I used WS API in Play framework:
WS.url(server + "/track/message").post(Json.toJson(newUser)).map { response =>
println(response.body)
true
}
The problem is resovled but not solved, won't work on a solution based on Play.
in the silverstripe backend I´m managing certain PageTypes via a ModelAdmin. That works fine so far, the only thing i can´t figure out is how to make a Page being "Published" when saving it.
Thats my code:
class ProjectPage extends Page {
public function onAfterWrite() {
$this->doPublish();
parent::onAfterWrite();
}
}
At the moment I can still see the ModelAdmin-created Pages in the Sitetree and I can see they are in Draft Mode. If I use the code above I get this error:
Maximum execution time of 30 seconds exceeded in
.../framework/model/DataList.php
Many thx,
Florian
the reason why you get "Maximum execution time exceeded" is because $this->doPublish(); calls $this->write(); which then calls $this->onAfterWrite();. And there you have your endless loop.
So doing this in onAfterWrite() or write() doesn't really work
you should just display the save & publish button instead of the save button
But I guess its easier said than done.
Well adding a button is actually just a few lines, but we also need a provide the functions that do what the button says it does.
This sounds like the perfect call for creating a new Module that allows proper handling of Pages in model admin. I have done this in SS2.4, and I have a pretty good idea of how to do it in SS3, but no time this week, poke me on the silverstripe irc channel on the weekend, maybe I have time on the weekend.
I found the same need/lack and I built a workaround that seems to work for me, maybe it can be useful.
public function onAfterWrite()
{
if(!$this->isPublished() || $this->getIsModifiedOnStage())
{
$this->publish('Stage', 'Live');
Controller::curr()->redirectBack();
}
parent::onAfterWrite();
}
Create a class that extends ModelAdmin and define an updateEditForm function to add a publish button to the actions in the GridFieldDetailForm component of the GridField.
public function updateEditForm($form) {
if ( ! singleton($this->owner->modelClass)->hasExtension('Versioned') ) return;
$gridField = $form->Fields()->fieldByName($this->owner->modelClass);
$gridField->getConfig()->getComponentByType('GridFieldDetailForm')->setItemEditFormCallback(function ($form) {
$form->Actions()->push(FormAction::create('doPublish', 'Save & Publish'));
});
}
Then create a class that extends GridFieldDetailForm_ItemRequest to provide an action handler for your publish button.
public function doPublish($data, $form) {
$return = $this->owner->doSave($data, $form);
$this->owner->record->publish('Stage', 'Live');
return $return;
}
Make sure the extensions are applied and you're done.
Or, you could just grab all the code you need from GitHub.
