    need some help : trying to store my object's reference in table

    Another newbie question..

    I probably do the things the bad way, but here is my problem:
    I want to store in a table (name columnListOfGameTextBox ) all the instances of textfield that I dynamically create in my func

    It seems to work well but when I print my table, the first entry is crap. Others work well... any idea ?
    Does the way I want to do it is a foolish one ?
    local columnListOfGameTextBox ={{0,0},{0,0},{0,0},{0,0}}
 
function createTextboxStage()    -- **********creation des txtfields du stage
 
		for i=1, 4 do   	
			for j=1, 2 do
				local txtbox = TextField.new(nil, "ABC")
				stage:addChild(txtbox)
 
				columnListOfGameTextBox[i][j]= txtbox   -- here I add the instance to my table
			end
		end
 
	printtbl(columnListOfGameTextBox)
 
end
 
function printtbl( t,tab,lookup )
    local lookup = lookup or { [t] = 1 }
    local tab = tab or ""
    for i,v in pairs( t ) do
        print( tab..tostring(i), v )
        if type(i) == "table" and not lookup[i] then
            lookup[i] = 1
            print( tab.."Table: i" )
            printtbl( i,tab.."\t",lookup )
        end
        if type(v) == "table" and not lookup[v] then
            lookup[v] = 1
            print( tab.."Table: v" )
            printtbl( v,tab.."\t",lookup )
        end
    end
end
 
createTextboxStage()
    any idea ? 8-}

      when I print my table, the first entry is crap. Others work well... any idea ?
      I get this output...

      1 table: 048A7C08
      Table: v
      1 0
      2 0

      2 table: 048A8580
      Table: v
      1 0
      2 0

      3 table: 048A7EC8
      Table: v
      1 0
      2 0

      4 table: 048A7F18
      Table: v
      1 0
      2 0

      Not sure what you mean about the first entry. What output did you want...? (I'm not sure what exactly you're trying to do...)

      I leave the 'problem' line commented in the sample code.

      try it now (example above shows the pb)

      here is the output I get :

      When presenting a problem it's best to explain what you're trying to achieve, how you're trying to achieve it, and the minimum amount of code needed to demonstrate the difficulty. Comments and meaningful variable names would also help. Otherwise it's too much like hard work. ;)

      (First the "printtb1" function is called with a single argument, then it calls itself with three arguments. I know Lua is fairly carefree about this kind of thing, but since it's apparently producing the wrong output the first time, I'm wondering if it's initially working with the wrong parameters. I don't understand what they should be though.)

      I really don't know what ur talking about :-/ Everything looks extremly clear... for me :D
      I'm going to clean the code a "little bit" or, better, make a simplified version and try to explain the goal behind that mess

      thx BJG
