$paginator = new Paginator([
    'builder'  => $builder->createBuilder(),
    'limit' => 10,

Resolved

This is still happening BTW. This is not resolved. I get the errors when accessing the data from a view variable that is set with:

$this->view->setVar('example','Example::findFirst(['blah_blah_opts'])

This view var is set AFTER I paginate(); the Model. I am using the Model Adapter for this. Running almost identical server setup as described in OP's ticket.

[niden]

@eklect Are you using the latest Phalcon? This was addressed in 4.0.1 from what I see.

[eklect]

I currently am running 4.0.5

@eklect I tried reproducing this but am not having much luck.

I created this test based on the input of this issue:

https://github.com/niden/cphalcon/blob/T14639-undefined-index-di-2/tests/database/Paginator/Adapter/QueryBuilder/PaginateCest.php#L223

And the tests pass just fine:

https://github.com/niden/cphalcon/runs/511189972?check_suite_focus=true

(you can expand the MySQL test run - you will see it's all green).

Any more input you can offer?

[eklect]

My bug I saw wasn't on the QueryBuilder Adapter, but on the Model adapter. I was experiencing the same issues but on a different adapter. My suspicion is that the QueryBuilder bug was fixed, but there might be one on the Model Adapter? That's about as far as I got on troubleshooting it before writing a "quick & dirty" workaround.

[niden]

Gotcha. I will write a test for the model one and see if I get a fail on it.

[niden]

@eklect No luck in reproducing it

Ok Thanks for looking into that for me @niden . Appreciate the help greatly. Thank you again for all your hard work! Phalcon is my absolute fav!
