Doing a compareWith, for the purpose of when I edit, the dropdowns may already be filled with the assigned values. By doing this, I get this error:
Uncaught (in promise): Error: Value must be an array in multiple-selection mode.
I honestly do not know where he asks for this array as the error says. Here's my html
<div class="container">
<div class="row">
<div class="col-md-12">
<table class="table table-striped table-bordered">

This is my Component . I put all of it, but it's the compareValues method
export class ApplicabilityComponent implements OnInit {
createForm: FormGroup;
public dataSource: Model.ApplicabilityItem[];
public dataSourcePayment: Model.TypePaymentItem[];
public dataSourceDelivery: Model.TypeDeliveryItem[];
public form:any;
constructor(private _applicabilityService: ApplicabilityService,
private builder: FormBuilder,
private route: Router) {}
ngOnInit() {
this.onGet();
this.initDefaultForm();
}
initDefaultForm() {
this.createForm = this.builder.group({
id: '',
name: '',
context: '',
typeDeliveryDetailsModels: [],
typePaymentDetailsModel: [],
marketPlace: false
});
}
onCreate(){
this.route.navigate(['create-aplicability']);
}
onDelete(aplicabilidade: Model.ApplicabilityItem) {
if (confirm('Deseja excluir o operador: ' + aplicabilidade.name + '?')) {
this._applicabilityService
.delete<any>(aplicabilidade.id)
.subscribe((res) => {
this.onGet();
});
}
}
onGet(){
this._applicabilityService
.getAllAplicability<Model.Result<Model.ApplicabilityItem>>()
.subscribe((data: Model.Result<Model.ApplicabilityItem>) =>{
this.dataSource = data.itens;
});
this._applicabilityService
.getAllDelivery<Model.Result<Model.TypeDeliveryItem>>()
.subscribe((data: Model.Result<Model.TypeDeliveryItem>) => {
this.dataSourceDelivery = data.itens;
});
this._applicabilityService
.getAllPayment<Model.Result<Model.TypePaymentItem>>()
.subscribe((data: Model.Result<Model.TypePaymentItem>) => {
this.dataSourcePayment = data.itens;
});
}
initEditAplicabilidade(aplicabilidade: any){
aplicabilidade.edit = true;
this.createForm = this.builder.group({
id: aplicabilidade.id,
name: aplicabilidade.name,
context: aplicabilidade.context,
typeDeliveryDetailsModels: aplicabilidade.typeDeliveryDetailsModels,
typePaymentDetailsModel: aplicabilidade.typePaymentDetailsModels,
marketPlace: aplicabilidade.marketPlace
});
}
checkEdit() {
if (this.dataSource == null || this.dataSource.length == 0) return false;
return this.dataSource.filter((item: any) => item.edit === true).length == 0;
}
onUpdate(){
let formValue = this.createForm.value;
this._applicabilityService.update<Model.Result<Model.ApplicabilityItem>>(formValue)
.subscribe(success =>{
this.onGet();
},
error =>{
}
);
}
compareValues(c1: Model.TypePaymentItem, c2: Model.TypePaymentItem): boolean{
debugger;
return c1 && c2 ? c1.id === c2.id : c1 === c2;
}
}
And my model
export interface ApplicabilityItem{
id: string,
name: string,
context: string,
typePaymentDetailsModels: TypePaymentItem,
typeDeliveryDetailsModels: TypeDeliveryItem,
marketPlace: boolean
}
export interface TypePaymentItem{
id: string,
sgpTypePaymentId: number,
name: string
}
export interface TypeDeliveryItem{
id: string,
sgpTypeDeliveryId: number,
name: string
}
What am I missing?
