TYPO3 Core

Got some strange caching problems with the exbase propertyMapper that results in a validation error of a child property because that property isn't correct loaded/fetched.

I get this message when it goes wrong:

BeechIt\Contactpersons\Controller\ContactPersonController->showAction()

Turns out that there is a validation error on the title property of a child object of the requested object.

Did some further debugging and when it goes wrong the debug of the child object looks like:

  mainCategory => BeechIt\Contactpersons\Domain\Model\Category [prototype][persistent entity] (uid=76, pid=20)
      sorting => NULL
      title => '' (0 chars)
      description => '' (0 chars)
      icon => '' (0 chars)
      parent => NULL
      uid => 76 (integer)
      _localizedUid => 76 (integer)modified
      _languageUid => NULL
      pid => 20 (integer)

When it goes right the debug of the same object looks like:

   mainCategory => BeechIt\Contactpersons\Domain\Model\Category [prototype][persistent entity] (uid=76, pid=20)
      sorting => 1280 (integer)
      title => 'Specialisten' (12 chars)
      description => '' (0 chars)
      icon => '' (0 chars)
      parent => TYPO3\CMS\Extbase\Domain\Model\Category [prototype][persistent entity] (uid=72, pid=20)
      uid => 76 (integer)
      _localizedUid => 76 (integer)modified
      _languageUid => 0 (integer)modified
      pid => 20 (integer)

Looks like the language overlay does not happen (correct) when it goes wrong. See the difference in the _languageUid property.

Problem is that I am not able to tel/force how to reproduce the problem. After a while of debugging it just works again. Looks like a cache is cleared somewhere (auto expire of some exbase cache).

The TCA looks like:

'main_category' => array(
            'exclude' => 1,
            'l10n_mode' => 'exclude',
            'label' => 'LLL:EXT:contactpersons/Resources/Private/Language/locallang_db.xlf:tx_contactpersons_domain_model_contactperson.category',
            'config' => array(
                'type' => 'select',
                'foreign_table' => 'sys_category',
                'foreign_table_where' => ' AND sys_category.sys_language_uid IN (-1, 0) ORDER BY sys_category.sorting ASC',
                'MM' => 'sys_category_record_mm',
                'MM_opposite_field' => 'items',
                'MM_match_fields' => array(
                    'tablenames' => 'tx_contactpersons_domain_model_contactperson',
                    'fieldname' => 'main_category',
                ),
                'renderMode' => 'tree',
                'treeConfig' => array(
                    'parentField' => 'parent',
                    'appearance' => array(
                        'expandAll' => FALSE,
                        'showHeader' => FALSE,
                        'maxLevels' => 99,
                    ),
                ),
                'size' => 10,
                'autoSizeMax' => 20,
                'minitems' => 0,
                'maxitems' => 1
            ),
        ),

And my model:

    /**
     * Department
     *
     * @var \BeechIt\Contactpersons\Domain\Model\Category
     * @lazy
     */
    protected $mainCategory;

    /**
     * Get main category
     *
     * @return \TYPO3\CMS\Extbase\Domain\Model\Category
     */
    public function getMainCategory() {
        return $this->mainCategory;
    }

    /**
     * Set main category
     *
     * @param \TYPO3\CMS\Extbase\Domain\Model\Category $category
     */
    public function setMainCategory($category) {
        $this->mainCategory = $category;
    }

Where \BeechIt\Contactpersons\Domain\Model\Category extends \TYPO3\CMS\Extbase\Domain\Model\Category

The typoscript mapping for that

plugin.tx_contactpersons {
    persistence {
        classes {
            BeechIt\Contactpersons\Domain\Model\Category {
                mapping {
                    tableName = sys_category
                }
            }
        }
    }
}
