Wow, interesting. Great blog post. So am I correct to understand that newPanel in @richard9’s post #8 will remain as a table after the transition is completed (even though it won’t be holding the display group object) until its reference to the makePanel function is manually nil’ed, or until it is garbage collected?

Here you go
local group = display.newGroup()
function group:close()
local function clearGroup()
group:removeSelf()
group = nil
print( group )
end
-- Slide out the object
group.transition = transition.to(group, { y = group.y + group.height, time = 200, onComplete = clearGroup } )
end
local img = display.newRect( 0, 0, 200, 200 )
group:insert( img )
group:close()
timer.performWithDelay( 2000, function() print( group ) end ) Some reading:

Honestly don’t understand the second link at all; have no idea how a[{}] is valid. I imagine that’s just mumbo-jumbo for the career programmers.
The second link is also a bit verbose but I can sorta understand what’s going on. It sounds like what is being said is that you have to do both -> internally nil the group from within the function AND nil the external variable for it, as the the former is the only way to destroy the contents and the latter is the only way to destroy the reference?
