I cannot find general checklist - what to check when it is not called. Can you write it?
For example code snippets where validator is not being called:
$fieldOptions['constraints'] = [
new NotBlank($constraintOptions)
];
$builder->add(
$builder
->create($formField->getId(), EntityType::class, $fieldOptions)
->addModelTransformer(
new EntityCollectionToArrayTransformer($this->registry, $fieldOptions['class'])
)
);
