Configuration of EXT:extender - fields not visible in frontend

[Dani-mam]

We're in the process of updating a Typo3 page that had several fields added to tt_address. After updating EXT:extender to version 10.1.1. there is no frontend output of these fields anymore. The fields are visible in the backend and can be edited.

We've used this manual: https://docs.typo3.org/p/friendsoftypo3/tt-address/main/en-us/Development/ExtendTtAddress/Index.html#development-extend-ttaddress

Current Behavior
no frontend output of the additional fields

Expected behavior/output
The content of our fields should show up in the frontend.

Environment

• TYPO3 version(s): 12.4.18
• tt_address version: 9.0.1
• Is your TYPO3 installation set up with Composer (Composer Mode): no
• OS: Windows 10

Possible Solution
It looks like there were breaking changes in EXT:extender version 10. It would be nice, if the documentation of tt_address could be updated.

Additional context
Here is the code of our Address.php

<?php

namespace GeorgRinger\AddressField\Extending\Domain\Model;

class Address extends \FriendsOfTYPO3\TtAddress\Domain\Model\Address
{
    /** @var string */
    protected $adhinstitution = '';

    /**
     * @return string
     */
    public function getAdhInstitution()
    {
        return $this->adhinstitution;
    }

    /**
     * @param string $adhinstitution
     */
    public function setAdhInstitution($adhinstitution)
    {
        $this->adhinstitution = $adhinstitution;
    }
        
    /** @var string */
    protected $adhdepartment = '';

    /**
     * @return string
     */
    public function getAdhDepartment()
    {
        return $this->adhdepartment;
    }

    /**
     * @param string $adhdepartment
     */
    public function setAdhDepartment($adhdepartment)
    {
        $this->adhdepartment = $adhdepartment;
    }
    
    /** @var string */
    protected $adhstatus = '';

    /**
     * @return string
     */
    public function getAdhStatus()
    {
        return $this->adhstatus;
    }

    /**
     * @param string $adhstatus
     */
    public function setAdhStatus($adhstatus)
    {
        $this->adhstatus = $adhstatus;
    }    
}

ext_localconf.php

<?php

$GLOBALS['TYPO3_CONF_VARS']['EXTENSIONS']['tt_address']['extender'][\FriendsOfTYPO3\TtAddress\Domain\Model\Address::class]['address_field'] = 'my_extension/Domain/Model/Address';

We have the same problem with Typo3 12.4.20 (composer installation) / extender 10.1.1 / tt_address 9.0.1

[tntrpsw]

I could also reproduce the problem not being able to extend the table with own/custom fields using TYPO3 12.4.22 (legacy, NOT composer based installation) and tt_address 9.0.1.

The custom fields became available using the "old" approach extending $GLOBALS['TYPO3_CONF_VARS']['SYS']['Objects'] within the "ext_localconf.php" and the "Configuration/Extbase/Persistence/Classes.php" files like so:

file "ext_localconf.php"

$GLOBALS['TYPO3_CONF_VARS']['SYS']['Objects'][\FriendsOfTYPO3\TtAddress\Domain\Model\Address::class] = [
  'className' => \<VENDORNAME>\<EXTENSIONNAMESPACE>\Domain\Model\Address::class
];

file "Configuration/Extbase/Persistence/Classes.php"

return [

  // ...

  \<VENDORNAME>\<EXTENSIONNAMESPACE>\Domain\Model\Event::class => [
    'tableName' => 'tx_calendarize_domain_model_event',
  ],

];

Btw: I would like to know, why this "old" way is not the preferred way and why the "extender" extension is needed. Is it, because fo more complex models it's not working?

[georgringer]

it is because xclassing works only 1 time, the extender makes it possible to extend a class multiple times. if you just need something in your project, feel free to do it this way!
