gc.addEventListener(GeocodingEvent.GEOCODING_FAILURE, geocoder_geocodingFailure);
gc.reverseGeocode(new LatLng(lat,lon));
}

but I keep getting an error

TypeError: Error #1009: Cannot access a property or method of a null object reference.

when i say geocoder = new ClientGeocoder();

Any Ideas?? I have even tried

geocoder = new ClientGeocoder(new ClientGeocoderOptions(…..));

but the result is the same. I am using map_flex_1_17.swc.

Thank you

Guys, I have an issue and I would appreciate it if somebody could help me.

As advised, I got an API Key, I downloaded the API, I copied the example source and everything worked nicely both locally and from a designated domain. Next morning, when I resumed working, however, the map would load but the geocoding would return the error:

“Unable to geocode address: …”

I get this effect again locally and from the respective domain. I also noticed that the example in this page returns absolutely the same error message, although it was working nicely yesterday.

Does anyone know what causes the issue?

Thanks!

Naso.

Sincerely,
Henry Mustafa

It seems that there is some information left in the cache after the initial loading so whenever you load google maps a second time into the same holder it will come to a crash.

What I did was to set a rootvariable with the initial loadingprocess to true. This helps to avoid to fire three critical commands a second time:

googleMap.addControl
googleMap.addControl
googleMap.setSize

Because setSize crashes too I resize the holder arround the Map (eg. Canvas or Box).

This workaround works fine for me now – yep!

Regards

Oliver

btw: Thanks a lot for this great blog!!!!

I got the same issue… Did you find a fix for it please?

Tnkx,

1. Make sure the google file swc is attached to the project via:
Project/properties/flex build path/library path/add swc
2. put the appid.txt (including your own google key) file on the webserver in folder src
3. put the google file swc on the webserver in the folder libs

this made it work for me. Thanks for this great code, you are the best!

cheers Don

ok I did everything above,
When I try the swf locally and click the button I get:

TypeError: Error #1009: Cannot access a property or method of a null object reference.
at myfolder/button_click()
at myfolder/__button_click()

When I try the swf after uploading to the webserver, I see the google white box, the address i put in and the button, plus a blank screen below (where the map should be). Pushing the button does nothing. Should this map_flex_1_5.swc file also be on the webserver?
How do i get the map to work? plse help!!!

ps. I had to change the location of this:

totally upward right below mx.application because during debugging it would give me error.

noob needs help :(
