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;
}
