重新加载formArray内部动态创建的formArray时出现无限循环

Question

我也有Client和Adresse类和组件，这些类和组件都是用angular制作的，客户端有一组adresse，我有form-group client-form，其中adresses为form-array。当我尝试用数据重新加载客户端和地址表时，最终导致地址表超出预期，并且它们为空。有什么问题吗？

 export class ClientService {
  private url = environment.apiUrl;
  private endpoint = 'client';
  constructor(private http: HttpClient, private fb: FormBuilder) {}

 formClient = this.fb.group({
    id: [null],
    nom_Client: ['', Validators.required],

    }),
    adresses: this.fb.array([this.addAdresseGroup()]),

  });
  addAdresseGroup() {
    return this.fb.group({
      id:[null],
      pays: ['', Validators.required],
      region: ['', Validators.required],
      cite: ['', Validators.required],
         })
  }
  addAdresse() {
    this.adresseArray.push(this.addAdresseGroup());
    console.log('adresse group array',this.addAdresseGroup());
    this.formClient.markAsDirty();

  }
  removeAdresse(index:number){
    this.adresseArray.removeAt(index);
  }
  get adresseArray(){
    return <FormArray> this.formClient.get('adresses');
  }}

export class DetailClientComponent implements OnInit {
  titre='Ajout nouveau client';
  dataModel: any; //active model
  constructor(
    private dialog: MatDialogRef<DetailClientComponent>,
    public clientServ: ClientService, private adresseServ: AdresseService
  ) {}

  ngOnInit() {
    if (this.clientServ.formClient.get('id').value) {
      this.loadClient();
       this.loadAdresse();
    }
      }

  loadClient() {
    this.clientServ
      .detailClient(this.clientServ.formClient.get('id').value)
      .pipe(take(1))
      .subscribe((res:Client) => {
       this.clientServ.formClient.patchValue(res as Client);     
        this.titre='Modification du client: '+this.clientServ.formClient.controls['nom_Client'].value;
      });
  }
loadAdresse(){
  this.adresseServ.listAdressebYClientId(this.clientServ.formClient.get('id').value).pipe(take(1)).subscribe((res:Adresse[])=>{
    for (let adres = 0; adres < res.length; adres++){
      const AdresseFormArray = this.clientServ.formClient.get("adresses") as FormArray;
      AdresseFormArray.push(this.clientServ.addAdresseGroup());}
       this.clientServ.adresseArray.patchValue(res);
    }
  );
}

  onClear() {
    this.clientServ.formClient.reset();
    // this.clientServ.adresseArray.reset();
  }
  onSubmit() {
    if (this.clientServ.formClient.valid) {         
      this.dialog.close(this.clientServ.formClient.value);
      this.onClear();
    }
  }
  onClose() {
    this.clientServ.formClient.reset();  
    this.clientServ.adresseArray.reset();  
    this.dialog.close();
  }
  displayaddAdress(a:FormArray,b:number):boolean{

    return a.length>b+1;
  }
  displayRemoveButton(a:FormArray){
  return a.length===1;
  }

 <div formArrayName="adresses" class="box">
                <div *ngFor="let gr of clientServ.adresseArray.controls; let i= index" [formGroupName]="i">

                  </mat-form-field>
               <div class="controles-container">

                  </mat-form-field>
               </div>
               </div>
            </div>
           </div>

例如，客户端有2个地址，实际的输出是预期的2个地址，并且只要关闭并重新加载该组件，就会有更多的空地址，那么如何解决呢？预先感谢您的回答。
