event.isError

Overview

Indicates whether the server returned an error rather than a location.

Normally this will be false, but in the error case it will be true (and the other event attributes will be empty). event.errorMessage will contain a string describing the error.

Example

local function mapLocationHandler( event )
    -- handle mapLocation event here
    if event.isError then
        print( "Error: " .. event.errorMessage )
    else
        print( "The specified string is at: " .. event.latitude .. ", " .. event.longitude )
    end
end

myMap:requestLocation( "1900 Embarcadero Road, Palo Alto, CA", mapLocationHandler )
