#### _ **Product/components** used and **version/fix** level:_

Microservice SDK 1018.510.0

#### _Detailed explanation of the problem:_

We’re using the SDK and observed a strange behavior. We use `EventListeners` to react on `MicroserviceSubscriptionAddedEvents`:

```auto
    @EventListener
    public void onMicroserviceSubscriptionAddedEvent(final MicroserviceSubscriptionAddedEvent event) {
        logger.info("MicroserviceSubscriptionAddedEvent: {}", event);
    }

```

This worked very good until we added a @PostConstruct block which runs some logic on the bootstrap tenant:

```auto
    @PostConstruct
    void init() {
        String bootstrapTenant = platformProperties.getMicroserviceBoostrapUser().getTenant();
        logger.info("bootstrapTenant: {}", bootstrapTenant);
        subscription.runForTenant(bootstrapTenant, () -> {
            logger.info("running in bootstrapTenant: {}", bootstrapTenant);
        });
    }

```

Independently of what is executed within the `runForTenant` block (even if it is empty): as a result, the `MicroserviceSubscriptionAddedEvent` is **not** received anymore and therefore the `onMicroserviceSubscriptionAddedEvent` method is **not** invoked!  
As a side note: the `MicroserviceSubscriptionsInitializedEvent` is still received.

Now we wonder why that `runForTenant` block with the `bootstrapTenant` is a problem? Can someone explain?

Thanks a lot,  
Michael

I cannot explain it but I recognized the same behavior sometime ago. I think I raised a support incident but couldn’t find it anymore. The solution was that you can only use one of them at a time. As the `onMicroserviceSubscriptionAddedEvent` is called on every startup and when a new tenant is added it should be where you should place your logic und you don’t need the `init()` anymore.

Thanks @Stefan_Witschel for the feedback. While I still dont understand why we cannot use both approaches, we now use a different workaround: we listen to the `MicroserviceSubscriptionsInitializedEvent` and do the initialization in there by invoking the `subscription.runForTenant()`.
