Angular form group: cannot find control with unspecified name attribute
I'm having a problem with my Angular app.
I'm trying to create 3 forms.
Here is my template:
<div *ngFor="let item of formNames; index as i" >
{{formNames[i]}}
<form [formGroup]='formFields[i]'>
<label>
Name:
<input type="text" [formControl]="formFields[i].name">
</label>
<label>
All:
<input type="text" [formControl]="formFields[i].all">
</label>
<label>
Done:
<input type="text" [formControl]="formFields[i].done">
</label>
<label>
Ctrl:
<input type="text" [formControl]="formFields[i].ctrl">
</label>
<label>
Rjct:
<input type="text" [formControl]="formFields[i].rjct">
</label>
</form>
</div>
The problem is that when the page loads, it renders only the first {{formnames[i]}}. Console says "ERROR Error: Cannot find control with unspecified name attribute".
Here is the code I use to render FormGroups:
export class TableDataFormComponent {
formFields: Array<any> = fields;
formNames = FORMINPUTS;
say = f;
}
let f = function() {console.log(this.formFields); };
const FORMINPUTS: Array<string> = ;
TableHeaders.HEADERS.forEach((item) => {
FORMINPUTS.push(item);
});
let fields: Array<FormGroup> = ;
for (let i = 0; i < FORMINPUTS.length; i++) {
fields[i] = new FormGroup({
name: new FormControl(''),
all: new FormControl(''),
done: new FormControl(''),
ctrl: new FormControl(''),
rjct: new FormControl('')
});
}
Here is the video of the problem: https://yadi.sk/i/4GnZpJLV38oWMg
Stackblitz for some reason is not working for my project, but the source code is here: https://stackblitz.com/github/kulaska/Table-app/tree/adding_forms_branch
I don't understand why data renders after interacting with buttons or input elements. It somehow triggers creating of new FormGroup.
Obviously, I need all of them to be created at the same time, without interacting with DOM.
Has anyone had the same issue? What do I do to solve this?
I'd really appreciate your help

Your best bet is to use the FormBuilder.
this.formBuilder.array([ this.createItem() ])
createItem(): FormGroup {
return this.formBuilder.group({
name: '',
all: '',
done: '',
...
});
}
And your template will need to useformArrayName="fields" and [formGroupName]="i"
