Hi,

I have a button which when pressed should execute a file download (the browser 
open a filebrowser to save the file). I do this with a window.open(url) call in 
the execute event. This works but how can I react on errors on the server side, 
for example showing a message if the file as not found. The window.open makes 
this difficult.

Is there a better way to do it?

Thanks,
 Michael
