Code review comment for lp:~verzegnassi-stefano/ubuntu-docviewer-app/fix-1544149

Tested this on OTA-9. It brings up the document selector, and I can select a document to transfer. However when I then press the tick in the header, nothing happens. I get a vibrate so it did notice I pressed the tick, but it never transfers the file. The document selector still works, I can select and unselect documents, but I can never transfer them.
