My game has a solve a jumbled word round, All the letters are displayed as tiles and you must drag them into answers spaces to solve the word. Here is my Event Handler for dragging and dropping the tiles on an answer space
local function onTouch( event )

-- Make target the top-most object
local parent = t.parent
parent:insert( t )
display.getCurrentStage():setFocus( t )
-- Spurious events can be sent to the target, e.g. the user presses
-- elsewhere on the screen and then moves the finger over the target.
-- To prevent this, we add this flag. Only when it's true will "move"
-- events be sent to the target.
t.isFocus = true
-- Store initial position
t.x0 = event.x - t.x
t.y0 = event.y - t.y
elseif t.isFocus then
if "moved" == phase then
-- Make object move (we subtract t.x0,t.y0 so that moves are
-- relative to initial grab point, rather than object "snapping").
t.xScale = 1.7
t.yScale = 1.7
t.x = event.x - t.x0
t.y = event.y - t.y0

end When a tile is placed I am flagging the container I dropped it onto as occupied, this stops any other tiles from being allowed to drop onto it. My question is how to release this container if the tile is removed, at the moment, when I drag a tile back off, the container is still being read as occupied. I have a recall button in my app that recalls all the tiles to their original position and sets the isOccupied back to false, but I really want to know how to do it for just one tile when it is moved off the container
