升级到RC5后,我们开始出现此错误:
ngModel cannot be used to register form controls with a parent formGroup
directive.
Try using formGroup's partner directive "formControlName" instead. Example:
<div [formGroup]="myGroup">
<input formControlName="firstName">
</div>
In your class:
this.myGroup = new FormGroup({
firstName: new FormControl()
});
Or, if you'd like to avoid registering this form control,
indicate that it's standalone in ngModelOptions:
Example:
<div [formGroup]="myGroup">
<input formControlName="firstName">
<input [(ngModel)]="showMoreControls" [ngModelOptions]="{standalone: true}">
</div>
看起来在RC5中这两个不能再一起使用,但是我找不到替代解决方案。
这是产生异常的组件:
<select class="field form-control" [formGroup]="form" [(ngModel)]="cause.id" [name]="name">
<option *ngFor="let c of causes" [value]="c.text">{{c.text}}</option>
</select>
FormsModule
和ReactiveFormsModule
