if object,_functionListener, touch or object._functionListeren.tap or object._tableListener.touch or object._tableListener.tap then

#22

Tried that, but getting error that the _functionListener is nil… or any of the above variations.  Here is my code:

local stage = display.getCurrentStage()   for a = 1, stage.numChildren,1 do       if stage[a].x then      print ("stage Object type = " .. type(stage[a]) .. "  object = " .. tostring(stage[a])          .. " x=".. stage[a].x .. ", y=".. stage[a].y .. ", w=".. stage[a].width .. ", h=".. stage[a].height);         if stage[a].\_functionListener.touch or stage[a].\_functionListener.tap or stage[a].\_tableListener.touch or stage[a].\_tableListener.tap then             print("has a listener")         end     end   end  

Here’s the error:

attempt to index field ‘_functionListener’ (a nil value)

All of these objects on this particular scene have either a tap or touch listener and function.

try adding ~= nil to each condition check

#24

already tried that, no matter what, all those are always nil.  But on this scene, all the display objects have either a tap or touch listener. 

#25

need to check for _functionListener then for _functionListen.touch and tap. then same for _tableListener

#26

Please keep in mind that our standard is to prefix **private** variables and methods with an underscore.  We are subject to change these attribute and method names at any time and without warning.  Use this technique at your own risk.

#27

both stage[a]._functionListener and stage[a]._tableListener are nil on all of the objects.
