[AngularJS] Re: Data not refreshed after Deleting from List
You are right Mr. Sander. The service is returning empty response. I am reading to rectify that. Thanks for your kind support.

Hi Partha, > The alerts I have placed are never fired. You mean the alerts in your first msg? If those are not fired, the response from your node server is not reaching back your app. I just noticed you are returning a 201. This might be the problem. Can you try with a code 200? (BTW 201 means a successful creation, that's a strange response on a delete...) Also, you should add an error-handling part in your service. checkout how to handle errors in observables. hint the CatchError operator is your friend.

[AngularJS] Re: Data not refreshed after Deleting from List
Dear Mr. Sander,
I have subscribed to the listener in ngOnInit().
The code is given below. I have doubt whether this is okay.
This code I had written in ngOnInit(). Later I moved it to a function so
that I could call it from ngOnChange() as well. However, I am certain this
approach is not correct.
Please advice.
Regards,
Partha
ngOnInit() {
this.refresh();
}
refresh() {
this.isLoading = true;
this.currencyService.getCurrencies();
this.currencySubscription = this.currencyService.getCurrencyUpdatedListener
()
.subscribe( (currencies: Currency[]) => {
this.currencyList = currencies;
this.currencyData.data = this.currencyList;
});
this.currencyData.paginator = this.paginator;
this.currencyData.sort = this.sort;
this.isLoading = false;
}

Hi Partha, Your code is ok. If the currency is not disappearing from the view, the mistake is not in this part. Are you sure you subscribed to the currencyListUpdated observable?
