Problem with File Upload in the Backend

[svenkeil]

Hello Helmut,

I have used some of your example extension files in my own extension (typo3 8.7.10) to manage file uploads. It's one of the best examples I've found for uploading typo3 files. Thank you for your good work.

I am using your UploadedFileReferenceConverter and your UploadViewHelper. Everything works fine on createAction. In the UpdateAction I always get the error:

• "The identity property "NAME-OF-NEW-IMAGE" is no UID. "

Do you have any idea why this error only occurs when updating the data?

Best regards Sven

OK, just for the records: I've double checked everything and simply forgot to add enctype="multipart/form-data" to my existing form. Thanks @helhum for this great and easy to use example
