Very helpful Matti, thanks for this!
I’m encountering one issue with the DynamicFileDownloader (0.4.0) though:
Sometimes the downloads are not working and the browser ends up just showing the url with the UUID in the address bar. After using the Firefox inspector, I could see following error: NS_BINDING_ABORTED (also the XHR POST http://localhost/app/?v-r=uidl&v-uiId=20 before failed)
It does not seem to have anything to do with the file contents because sometimes it works, sometimes it doesn’t… Has someone experienced similar problems?
