[SOLVED] How to setup the selectable pages in a Page Reference Field inside a Repeater?!

[Pixrael]

I have a Page Reference Field and I need to select only the children pages of the current page where the field is edited. But the problem here is that the field is inside a Repeater, and the repeaters are actually another pages in the tree.. so where I can do easily using a custom code in ready.php like this:

$wire->addHookAfter('InputfieldPage::getSelectablePages', function($event) {
  if($event->object->hasField == 'page_list') {
    $event->return = $event->arguments('page')->children;
  }
});

this don't work If the field is inside a Repeater.. I need to get the related page to the current repeater page to get the children, but how to do it?

Try using ... ('page')->getForPage()->children instead

I try it but in the Field setting page I get this error:

ProcessField: Method Page::getForPage does not exist or is not callable in this context

and in the Page edit i get this: 

InputfieldRepeaterMatrix: Repeater 'layouts_main' preload 'page_list': Method Page::getForPage does not exist or is not callable in this context

This one seems to work for me. 

$wire->addHookAfter('InputfieldPage::getSelectablePages', function($event) {
    if($event->object->hasField == 'page_list') {
        $event->return = $event->object->hasPage->children;
    }
});

Edit:

Nope. ->hasPage gives the repeater item page (not exactly, keep reading), ->arguments('page') gives the page being edited.

$this->addHookAfter('InputfieldPage::getSelectablePages', function (HookEvent $e) {
    if ($e->object->hasField->name != 'testReference') return;
    $e->return = $e->arguments('page')->children;
});

Weird thing is that InputfieldPage::getSelectablePages is called twice for every new repeater item. On the first call, hasPage and arguments('page') are identical, but on the second call, hasPage is the repeater item, arguments('page') is the page being edited.

So using the argument seems to be the better option.
