[xwiki-users] Display external data using LiveTable Macro

Hi! Does anybody know how to display some external data using LiveTable macro? I can see in doc, that there is an 'url' alternative datasource (alternative to className and resultsPage), but I cannot find any examples using it. I've tried to write to the text file the JSON output used by the macro, then I put the file on some http server and try to use its url in macro invocation, but it does not work.
