The LabelList below is not displaying on the screen. How to fix this? Thanks!

sub showLabelList()
    m.top.visible = false
    m.currentexample = createObject("roSGNode", "LabelListExample")
    m.top.appendChild(m.currentexample)
    m.currentexample.setFocus(true)
    m.buttons.setFocus(false)
end sub

Have you tried removing /. commenting out the line that says 

 m.top.visible = false

Thanks for your reply. I tried that but all the buttons, descriptions, etc from this DetailsScreen become mixed with the LabelList. I tried to set:

    m.buttons.visible = false
    m.poster.visible = false
    m.background.visible = false
    m.description.visible = false

This is the crash log:

041:  Sub OnFocusedChildChange()
042:*     if m.top.isInFocusChain() and not m.buttons.hasFocus() and not m.videoPlayer.hasFocus() then
043:          m.buttons.setFocus(true)
044:      end if
045:  End Sub
Interface not a member of BrightScript Component (runtime error &hf3) in pkg:/components/screens/DetailsScreen/DetailsScreen.brs(42)
042:     if m.top.isInFocusChain() and not m.buttons.hasFocus() and not m.videoPlayer.hasFocus() then

But it messed up the focus. Any suggestions?

seems like you're on the right track but you need to debug that crash.  does m.videoplayer exist at that point?  maybe you need to set focus onto the labellist if it's not already?

Thanks for your help, my friend. I've put some if statements and for now it seems to work just fine.
