Examining the validation

It's interesting to see that the 'checkbox-group' uses 'formControlName="store_ids"'. The user is puzzled why validators aren’t firing when stores are checked. This setup suggests a custom component is at work.

Adjusting validation

OK, let's see. 'store_ids' as an array needs a FormArray. 'Validators.required' won't work with a simple string. Setting it as a FormArray ensures proper validation.

Noticing the issue

'store_ids' as an empty array might pass validation since Angular considers it valid. A custom validator is needed to ensure 'store_ids' isn't empty.

Assessing custom controls

OK, let's think this through: custom form controls like 'checkbox-group' might not link well with Angular's validation system, so the field status isn't transmitted correctly.

Setting up custom controls

Hmm, I’m curious if a custom 'ControlValueAccessor' is needed for the 'checkbox-group' to ensure 'store_ids' isn't empty by default. This seems like a crucial step.

Shifting focus

OK, we’re thinking about how a custom 'checkbox-group' without 'ControlValueAccessor' keeps 'store_ids' empty. This might be why Angular's 'required' validator isn't working.

Pinpointing validation clues

OK, let's identify the user's validation errors by examining 'personaForm.controls.store_ids.errors'. Ensuring 'store_ids' is an array and using 'ControlValueAccessor' with custom elements or libraries is crucial.

Overcoming empty array validation

I'm working through whether Angular's 'required' validator sees an empty array as valid. Using a custom validator or checking length might be necessary for clarity.

Revisiting empty array validation

I'm piecing together details on Angular's 'required' validator. It sees an empty array as invalid, and issues might stem from incorrect control references in the template or 'checkbox-group' value updates.
