Geocode Server Problem

weeyeo

Hello,
I am using 'Geode an address' sample from resources website with my own geocode server services for a test but I got some ActionScript error messages after click on"Find Adress" button.  On my own services, I only have 'Street' for address Fields.  Can someone let me know why I got these messages?
*********************
Here are ActionScript error:

TypeError: Error #1010: A term is undefined and has no properties.

    Problem:
        How to find the address (aka geocoding) for a certain address?

    Solution:
        Use the addressToLocations() method on the Locator.

    This sample takes a user-provided address and sends it to the
    server for geocoding.  When the response comes back, the OnResult()
    function creates a graphic for the result and then sets the scale
    appropriately based on if the match was a "street", "city" etc match.

Thank you very much.

wyeo,

   your locator service probably does not have a Loc_name field that it returns so you are getting the error.

Robert,
Thank you for pointing it out.

Wyeo
