Eu tenho uma matriz de formulário dentro de um formbuilder e estou alterando formulários dinamicamente, ou seja, ao clicar em carregar dados do aplicativo 1 etc.
O problema que estou tendo é que todos os dados carregam, mas os dados no formarray permanecem e apenas concatam os itens antigos com os novos.
Como faço para limpar o formarray para ter apenas os novos itens.
Eu tentei isso
const control2 = <FormArray>this.registerForm.controls['other_Partners'];
control2.setValue([]);
mas não funciona.
Alguma ideia? obrigado
em nginit
ngOnInit(): void {
this.route.params.subscribe(params => { alert(params['id']);
if (params['id']) {
this.id = Number.parseInt(params['id']);
}
else { this.id = null;}
});
if (this.id != null && this.id != NaN) {
alert(this.id);
this.editApplication();
this.getApplication(this.id);
}
else
{
this.newApplication();
}
}
onSelect(Editedapplication: Application) {
this.router.navigate(['/apply', Editedapplication.id]);
}
editApplication() {
this.registerForm = this.formBuilder.group({
id: null,
