CF8 - PHP Event & File Upload

File upload doesn't work if it's in a PHP event! If I push it outside the event, it works.

I miss the runconditions from CF7...

it doesn't work in the mutlifield area either.

Ok, I work around the problem as follows: File field is no longer a mandatory field, an additional page is added, here I check whether a file has been uploaded, if yes: virus scan and further, if no: error message. Not pretty, but it works.
