ATK4 Autocomplete issue - php

Question

I'm new to ATK4.
I'm trying to implement an Autocomplete field, but I had only an error when I try to define the field.
I'm running all on a MAC with the last version (4.2.4) of ATK4. All other functions (field types) seems to work well, but when I define a field of type autocomplete I get the same error I saw on the example: http://codepad.agiletoolkit.org/autocomplete
The case is I defined a model:
class Model_Agenda extends Model_Table {
public $entity_code='Agenda';
function init(){
parent::init();
$this->addField('DATE');
$this->addField('TIME');
$this->addField('DRIVERID');
$this->addField('STUDENTID');
$this->hasOne('STUDENTID')->display(array('form'=>'autocomplete/Basic'));
}
}
and then on my Page:
$form = $this->add('Form');
$form->addField('ReadOnly','Date')->Set($_GET['date']);
$form->addField('ReadOnly','Time')->Set($_GET['time']);
$form->addField('ReadOnly','Driver')->Set($_GET['driverid']);
$client=$form->addField('autocomplete','studentid');
something simple, but nothing, I cannot get the autocomplete field, I ever get an error that say that "autocomplete.php" doesn't exist (actually the file doesn't exist and I try to download the github module, but either that module includes this file), anyway the error I get is:
Exception_PathFinder, code: 0
Additional information:
file: Form/Field/Autocomplete.php

Someone could help me please?

You're talking about this add-on, right: https://github.com/atk4/autocomplete?
Looks like issue with PathFinder unable to find appropriate location of namespaced addons.
Please post here part of your API_Frontend class where you add additional locations to pathfinder and also tell me something more about your folder structure (in which folder you have put autocomplete add-on files).
ATK 4.2.4 version is not last. Can you try to upgrade ATK to version 4.2.5? It's not officially released, but is available in GitHub master branch here: https://github.com/atk4/atk4?
I hope everything will work with 4.2.5 version but if not, then I'll help you solve this issue.
And one more thing - if you're creating form fields manually, then you need to set Model for that $client field. I guess it can be done with $client->setModel('Agenda');
EDIT: correct answer
In line
$client=$form->addField('autocomplete','studentid');
you should write full autocomplete field class name with namespace like this:
$client=$form->addField('autocomplete/Basic', 'studentid');
One more thing to note is to use lowercase function name. So instead of Set() use set().
