[Flow] Property Mapping on creating of TYPO3.Media.Image via Ajax

[Daniel Völkel]

Hi everybody,

I built my own image upload based on the example from the Flow Cookbook[1] which worked fine so far.
Now I want to rebuild the upload to have an ajax based image upload. Unfortunately I keep getting errors on a wrong property mapping:

Exception while property mapping for target type "Vendor\PackageDomain\Model\Bild", at property path "image": It is not allowed to map property "resource".

The rendered formfield itself looks like this:
<input type="file" name="bild[image][resource] />

And I also attached some property mapping 

public function initializeCreateAction() {
	$propertyMappingConfiguration = $this->arguments->getArgument('bild')->getPropertyMappingConfiguration();
	$propertyMappingConfiguration->allowAllProperties();
	$propertyMappingConfiguration->setTypeConverterOption('TYPO3\Flow\Property\TypeConverter\PersistentObjectConverter', \TYPO3\Flow\Property\TypeConverter\PersistentObjectConverter::CONFIGURATION_CREATION_ALLOWED, TRUE);		
}

I have also built a similar and working ajax upload with TYPO3/Flow/Ressource which can't use here because I need the access to some image converting functions.

Do you have any idea what could be wrong?

Kind regards,
Daniel
