Just adding a little more information - the markers are visible on Chrome, Firefox and Safari. However, Firefox and Chrome (while being about to handle the exception and keep running javascript on the page) both report errors in their Javascript console. Here is the error in Chrome:

Did you get any response to this or resolve the issue? I'm getting a similar error for for the geometry library instead of adsense.

Yes, I am looking into it but your site is quite large and complex. Are you able to create an example with the least amount of code that still demonstrates the problem?

Thanks

@greg - this is the first response just now. Issue is not resolve yet.

Are you asking me (I reported the adsense bug) or [email protected]? 

The link I gave ( http://www.topix.com/map?node=city/san-francisco-ca&latest_version=1 ) is pretty much just big google map with a little bit of javascript to manage the markers. I am guessing if you just create a map with a lot of randomly created markers (say 100-300 markers) AND a Adsense Map Ad Unit... you should be able  to reproduce the error.

If it is my example. Please tell me what part of my javascript you are having trouble with... and I will try to simplify.

Thank you for looking at this issue.

I was referring to the topix link. It has almost 1000 lines in the file and is a bit of a mess to try and isolate what would be causing the error.

Hey you go... I've stripped it down to an example that is only 55 lines.

http://www.topix.com/map_bug (uses v=3.3 and has no errors)

http://www.topix.com/map_bug?latest_version=1 (uses latest version of api and show an invalid argument or "An invalid or illegal string was specified (88 out of range 42)" error in adsense.js).

Let me know if this is sufficient or if you want me to add/remove something from the example.

Thanks thats much easier to investigate now.

Hi, just checking back after a month. I see the status is still listed as "NeedsMoreInfo". I was wondering if you need anything more so as to change the issue status at least to "Confirmed".

Thank you for your time

The problem is in your JSON object you have a key "eventful_loaded": 1 which you are then trying to turn into a LatLng object.

You should validate that var latlng_pair = point.split(",") is actually of size 2 and will be a valid LatLng before you create the object.

Sorry, in my zeal to simply the original javascript code for you. I removed the some conditional checks in the that exist in the original code to handle these situations. I have added the checks in the sample code. Can you please reopen the bug and investigate? (I still see the error on IE8).

Thank you.

Bumping back to new until I verify - I do see the error in IE8 now - I just need to verify the cause :)

Actually, looking at your example in IE8 I am not able to see any errors. Do you still see it?

Thank you for the quick reply!

Yes... it happens inconsistently onload... but pretty reliably if I drag and map around a little. I suspect the error occurs when the Google Adsense for Map unit trying to refresh itself with a new ad (my guess).

Confirmed. You need to drag the map to cause the error.

This error is not related to markers at all - if you remove the markers the error still happens.
