When trying to access an array within a nested reactive form group, a linting error was encountered

I'm currently working on a method to delete rows from a dynamic form, but I am struggling to target the array.

The structure of my form group is as follows:

this.piForm = this.fb.group({
    milestoneSaveModel: this.fb.group({
        milestonesToCreate: this.fb.array([this.mileStoneCreate()]),
    }),
});

Here's what my delete method looks like so far:

deleteRow(index: number) {
    const control = <FormArray>this.piForm.controls['milestoneSaveModel'].controls['milestonesToCreate'];
    control.removeAt(index);
}

Even though the browser successfully triggers the action, my linter shows an error message saying

Property 'controls' does not exist on type 'AbstractControl'.

How can I address this linting error while keeping the functionality intact?

Answer №1

recommended code structure:

Replace the following syntax with this one: 
this.piForm.fetch('milestoneSaveModel').fetch('milestonesToCreate')

Answer №2

In order to proceed, it is essential to change the type of control to FormArray.

form.get('milestoneSaveModel').get('milestonesToCreate') as FormArray;
