Question

我将我的importantOwners作为一个数组，我将地址作为一个formGroup，一旦服务给我数据，我想将从服务中获得的值推送到表单中，我该怎么做？

this.significantOwnersForm = fb.group({
    significantOwners: this.buildSignificantOwnerArray()
});

buildSignificantOwnerArray() {
    this.significantOwners = this.fb.array([this.buildSignificantOwnerGroup()]);

    return this.significantOwners;
}

buildSignificantOwnerGroup() {
    return this.fb.group({
        name: '',
        address: this.fb.group({
            addressLine1: '',
            addressLine2: '',
            addressLine3: '',
            addressLine4: '',
            addressLine5: '',
            city: '',
            state: '',
            postalCode: '',
            countryCode: ''
        })
    });
}

setSelectedSignificantOwnersInformation() {
    let selectedMerchantsSignificantOwners = this.merchantInfo[this.selected[0].merchantNumber].significantOwners;
    let significantOwnersFGs = selectedMerchantsSignificantOwners.map(owner => this.fb.group(owner));
    let significantOwnerFormArray = this.fb.array(significantOwnersFGs);

    this.significantOwnersForm.setControl('significantOwners', significantOwnerFormArray);
}

我收到错误错误错误：找不到路径控件：'significantOwners - ＆gt; 1 - ＆gt;地址 - ＆gt; addressLine1'

找不到地址的任何内容。

更新：显示错误
