Yes. A little monkey-see, monkey-do programming based on your example got the job done.

I see that. clickCallbackClosure is actually called when the listener is being set up. I'll have to think about the whole concept and do some reading. > > Note that using a global variable inside an ordinary event handling > function won't work, because the global variable will be evaluated at > the time the function is invoked (the event fired), not the time that > the function was attached to the event. Yes. That's what I started with -- allPins[i] was getting evaluated when the event fired (and i had some quasi-random value). Very confusing to sort out. Re the "bug" where a stack of listeners seemed to be getting created by addListener I have now determined that they are getting added in another way. When a pin is created (hence allPins gets one element bigger) I recreate the whole map for reasons outside the scope of this thread. I had assumed that everything associated with the old map was blown away (I even set the map variable griddedMap to null) but that seems to not be the case. Hence my stack of listeners. So now I am using clearListeners to make sure that the old lsteners are gone when I put the pins and listeners onto the new map. I am also going to re- look the need to recreate the map. It might be overkill for what I am trying to do. Anyway, thanks a lot gents. You were a big help on what was a tough problem for me. -- You received this message because you are subscribed to the Google Groups "Google Maps JavaScript API v3" group.
