Download Widget redirecting me to a blank page

I´m having a problem with the Download Widget.
I created an action in a webscreen that dowloads a file, everytime I select a file from a table record list.
The first time I press the download eveything works fine, but if I press it again to download the same file or even a different one, I´m redirected to a blank page that has the same URL.
It seems that the action that downloads the file is not called, but yet I´m redirected to the same node with a blank page.

Please send us (to the espace that is having this behaviour. Give us also informaiton about the Hub Server and Service Studio versions that you are running/using.
