Hi -
I have a sub that handles certain empty feeds and uses roMessageDialog to tell the user that the feed is empty. After that, I wasn't sure how to properly send them back, so I had just started at the beginning again with

  screen=preShowHomeScreen("Blah", "")
  showHomeScreen(screen)

But now I noticed that if the user clicks 'up' from that point, they are at the 'Retrieving' screen from the previous empty feed and they need to hit up again.

So I am trying to correct this, I tried

  screen.close()
  screen=preShowHomeScreen("Blah", "")
  showHomeScreen(screen)

But then nothing happens at all when the user hits 'OK' the roMessageDialog doesn't go away.
I tried a few other variations of "return" but the 'Retrieving' screen is all I can get that way.

Now I see that my roMessageDialog is called from within

screen.SetContentList(getShowsForCategoryItem(category, m.curCategory))

so that's why the screen.close doesn't work... looks like this will take some serious hacking to change to do what I want... maybe I should just live with it.

Can anyone point me in the right direction for how to handle this?

OK I got it, wasn't that hard actually.
new code in appPosterScreen.brs:

    shows = getShowsForCategoryItem(category, m.curCategory)
    print "loaded feed has this many: "; shows.Count()
    if shows.Count() = 0 return -1
    screen.SetContentList(shows)
