[android-developers] error: this.L is null or not an object

Thu, 04 Sep 2008 23:07:30 -0700 

I have a page where I'm using the google maps api, and if I use IE,
I'll get this error about 40% of the time:

line: 744
char: 31
error: this.L is null or not an object

If I use firefox, I don't get this error at all.

As best as I can figure, this stems from the
geocoder.getLocations(address, addAddressToMap); method.  If I try the
geocoder.getLocationsAsync(address, addAddressToMap); method found in
many of the examples, I get an error saying that this object doesn't
support this method.

Here's my page:
