Description

When you use the BE module and you save a form default Value is set to ''
Then if you have some hook pre populating some field is having no effect as defaultValue: '' from Yaml file is having more priority.
I would like to think the way to fix it is not set defaultValue if it is empty, however I don't know which other implications could have.

hook function I'm using is


public function initializeFormElement(\TYPO3\CMS\Form\Domain\Model\Renderable\RenderableInterface $renderable)

Can you provide your code from the Hook and the formDefinition yaml (please anonymize it)?
Actually this should work.

            $renderable->setDefaultValue('foo');

This hook will be called after all properties from the prototype configuration are set in the form element but before the properties from
the form definition are set in the form element.
If you want to prefill form element data after the complete form element is configured you should use the afterBuildingFinished hook.
