I'm trying to setup external data sources for News Show Pro widget.
I'm able to use external RSS feed by simply entering URL next line to "Data source: " option set to "RSS feed".
But if I try to use "JSON file" or "XML file" option I get empty drop down box with just "Please select JSON file" or "Please select XML file". It seems that I have to setup such links somewhere else or this drop down box should be in fact a text field - same as when selecting "RSS feed"
