Hello! When I try to load data used http services, always need to do other action before my data load, never load automatically, for example my service is


listAll(): Observable<any> {
return this.http.get<Clients[]>(this.variables.getServiceEndpoint() + '/clients/all/', {})
.pipe(catchError(err => {
this.notAllowed(err);
return throwError(err);
}
)
);


In my OnInit have that code


this.service.listAll()
.subscribe(i => {
this.clients = i as Clients[];
});


and in my table use this information


<tbody>
<tr *ngFor="let clients of clients">


but never load alone, always need to click any bottom, for load

Can help me?

Thanks
