SimpleFileDownloader

I’ve tried to send 2 attachments to Nikolay Gorokhov but nothing: my thread is disappared. Now I try to upload my two projects on vaadin forum. The problem is that one project (prova) works, the second, exactly the same (demostene), doesn’t work. The second project was generated by spring boot initialzr, the first with normal system: new > maven > choose archetype. The goal of projects is starting downloading one file.

Attachment not working

I can download but I have to click twice. It seems the download stream keeps the last data set and never clears the buffer? Is there a way to fix this issue?

I try another time
