Magento – Can’t find customer attribute source model

eavsource-model

I have a module:

Model/SelectType.php

class NAME_CustomField_Model_SelectType
{
  public function toOptionArray()
  {
    return array(
      array('value' => '1', 'label' => '1'),
      array('value' => '2', 'label' => '2'),
      array('value' => '3', 'label' => '3'),
    );
  }
}

in my etc/config.xml I have:

<config>
    <modules>
        <NAME_CustomField>
            <version>0.1.1</version>
        </NAME_CustomField>
    </modules>
    <global>
        <models>
            <customfield>
                <class>NAME_CustomField_Model</class>
            </customfield>
        </models>
    </global>
...

Now, if I set in the DB (table: eav_attribute) source_model to: customfield/selectType it gives an error: Source model "customfield/selectType" not found.

UPDATE:
I've moved my file to: "code/core/Mage/Customer/Model/Customer/Attribute/Source" (for testing ofcourse) and changed the resource model to: customer/customer_attribute_source_selecttype
This works, so I think there is something in my /etc/*.xml that is wrong, but I can't seem to find what it would be… :-S

Your XML looks correct — although if Magento's loading the class from the Mage namespace that may be because your XML hasn't been loaded into the global configuration tree (cached XML, incorrect app/etc/modules file).

Your best bet is to debug things at the point where Magento looks into the configuration for your new class name

#File: app/code/core/Mage/Core/Model/Config.php
public function getGroupedClassName($groupType, $classId, $groupRootNode=null)
{
    //..
    $config = $this->_xml->global->{$groupType.'s'}->{$group};
    $className = null;
    if (isset($config->rewrite->$class)) {
        $className = (string)$config->rewrite->$class;
    } else {
    //..
}

Figure out why Magento can't find your base classname in the XML configuration, and you'll have your problem solved.
