PageTable page not being assigned to parent page

[Marc]

I have a template file that receives some form data that I save to a pageTable field. I use the pageTable to add notes to user profiles, so every user can have child pages containing a note and a date. Here's what I use:

$notes = $input->post->textarea('notes'); // Passed via javascript.
$customerId = $input->post->int('id');
$customer = $users->get($customerId);

$newNote = new Page;
$newNote->template = 'user-notes'; 
$newNote->parent = $customer; 
$newNote->of(false); // turn off output formatting before setting values
$newNote->save();
    
$newNote->title = 'user note';
$newNote->notes_date = date('Y-m-d H:i:s');
$newNote->notes = $notes;
$newNote->save();

// So far so good, but this bit does not work:
$customer->user_notes->add($newNote);
$customer->of(false);
$customer->save('user_notes');
// Just as an example, this part DOES work:
$customer->gender = 2;
$customer->save('gender');

The child page is created but it is not added to the user's 'user_notes' pageTable. If I place this code in my admin module, it works as expected. Any ideas what could be going wrong?

Edit: fixed it by switching these lines around:

$customer->of(false);
$customer->user_notes->add($newNote);

Now it works as expected. Strange it works in the other order on another page, but there you go.

Admin modules sometimes do run with output formatting of by default (depends on when they are executed), which would explain the behaviour.

It's something I'll keep in mind. Output format should be off before modifying a pagearray, check.

Just make sure to keep the right thing in mind: Output formatting needs to be of if you're editing any fieldvalue of a page, especially if you're trying to save it afterwards. There's no correlation to pagearrays per se.

Looks like I still don't quite understand. In a regular template file I added these tests, trying to remove a page from 'user_notes' which is a PageArray field:

$note = $pages->get(1259);
$customer = $note->parent;

$customer->user_notes->remove($note);
$customer->of(false);

$customer->save('user_notes');

^ Result: no error, but PageArray is not updated.

$note = $pages->get(1258);
$customer = $note->parent;

$customer->of(false);
$customer->user_notes->remove($note);

$customer->save('user_notes');

^ Result: "Field 'user_notes' from page 1172 is not saveable because it is a formatted value."

$note = $pages->get(1258);
$customer = $note->parent;

$customer->user_notes->remove($note);
$customer->of(false);
$customer->user_notes->remove($note);

$customer->save('user_notes');

^ Result: PageArray is successfully updated.

Why would I have to use the 'remove' method twice in order for this to work?
