patchEntity set date field to NULL

Hi, did somebody recognized already, that patchEntity might set a field (datefield) to NULL (probably during internal validation, may get more into details soon) ? It is also strange the the field is set dirty even the field have not changed or touched ?

DB error, constraint violation (cause NULL): request edit and just submit, leds to pickup NULL after patchEntity
No exception: request edit, just change one single field on the form gives correct value of pickup

controller:
$order = $this->Orders->patchEntity($order, $this->request->getData());
debug($this->request->getData());
debug($order);
exit; // only for debug
if ($this->Orders->save($order)) { // <== Exception of course because pickup is NULL)

template:
… form create …
echo $this->Form->control('pickup');

… form new

OUTPUT:
debug($this->request->getData());
[
‘user_id’ => ‘2’,
‘destination’ => ‘d’,
‘freetext’ => ‘df’,
‘pickup’ => ‘2020-05-21T10:10:20.000’,
‘orderstatus_id’ => ‘1’
]
debug($order);
object(App\Model\Entity\Order) {

'id' => (int) 12,
'user_id' => (int) 2,
'destination' => 'd',
'freetext' => 'df',
'pickup' => null,
'orderstatus_id' => (int) 1,
'modified' => object(Cake\I18n\FrozenTime) {

	'time' => '2020-02-27 00:25:38.000000+00:00',
	'timezone' => 'UTC',
	'fixedNowTime' => false

},
'created' => object(Cake\I18n\FrozenTime) {

	'time' => '2020-02-27 00:25:38.000000+00:00',
	'timezone' => 'UTC',
	'fixedNowTime' => false

},
'[new]' => false,
'[accessible]' => [
	'user_id' => true,
	'destination' => true,
	'freetext' => true,
	'pickup' => true,
	'orderstatus_id' => true,
	'modified' => true,
	'created' => true,
	'user' => true,
	'orderitem' => true,
	'orderstatus' => true
],
'[dirty]' => [

**‘pickup’ => true
],
‘[original]’ => [
‘pickup’ => object(Cake\I18n\FrozenTime) {

		'time' => '2020-05-21 10:10:20.000000+00:00',
		'timezone' => 'UTC',
		'fixedNowTime' => false
	
	}
],
'[virtual]' => [],
'[hasErrors]' => false,
'[errors]' => [],
'[invalid]' => [],
'[repository]' => 'Orders'

}

may be worth to check against this, … will come soon again

small update here from my side: I believe some RTFM exercise necessary here on my side and will come back soon :slight_smile:

https://book.cakephp.org/4/en/core-libraries/internationalization-and-localization.html#localizing-dates-and-numbers

quick solution can be to set (as the docu points to :wink: ):
put in controller before patchEntity (check format)
Type::build('datetime')->useLocaleParser()->setLocaleFormat('yyyy-MM-dd\'T\'HH:mm:ss');
