adding more files as allowed shows wrong message

[madmikede]

I set 'maxNumberOfFiles:5' in my code.
When adding more than the allowed 5 files (input multiple) the message "Max number of files exceeded" is shown for all files.
I expected, that the first 5 files are ok and the other files show this message.
It looks like _adjustMaxNumberOfFiles is running for every file before the output is rendered.

Don't know if this behaviour is wrong or not.

Thanks in advance.
