This Form is to register Users with an Image. After submit I check if there Name is all ready taken and look for other errors if there is an error I want that everything is still in the Form except the password. It is working with the Username but not with a file (Image). So how can I do that?

Answer

It is by default impossible to set a default value for a file picker due to security reasons
