GeoCode without any Result

[1A Parco-Service GmbH]

Hello,

I am a little bit confused about the handling of the geocode service.
Ok let me begin from the beginning:

I read some tutorials, examples and I have used the api.playground. The normal code for geocoding looks like this:

var searchManager = nokia.places.search.manager;

searchManager.geoCode({
	searchTerm: "Seeligenstadt, 07580 Seeligenstadt",
	onComplete: function(responseData, status) {
			if(status == "OK") {
				var locations = responseData.location;

				if (locations.length > 0) {
					// loop through the results here
				} else {
					alert("Your search produced no results!");
				}
			} else if (requestStatus == "ERROR") {
				alert("The search request failed.");
			}
		}
	});

There is no problem if the API found results. But as in this example with the searchTerm "Seeligenstadt, 07580 Seeligenstadt" just nothing happens.
There is no requestStatus = ERROR or locations.length = 0 to handle this case that the API can't found a result.
The onComplete function will not be called at all...

My current solution is a timeout. If the onComplete function wasn't called after a few seconds, I handle this as an non-result. I think that this is a very diry solution and thats why I ask here for help about this.

Is there any way to handle the "can't found anything" case better?

Ever find a better solution to this problem? I am having the exact same issue. Seems to be happening when the searchTerm is something that can't be geoCoded.

Nope, not yet. But my solution with the timeout works very well. ;-)

Could you show a small example? Thanks in advance.

Yeah sure:

function callbackFunction(response) {
	if(!response)
		alert("NO RESULT");
	else
		alert("GEOCODE OK");
}


nokia.Settings.set("appId", "--------------------------"); 
nokia.Settings.set("authenticationToken", "---------------------------");
var searchManager = nokia.places.search.manager;

// init timeout function
var searchTimeout = setTimeout(function() {
	callbackFunction(false);	
}, 3000);

searchManager.geoCode({
	searchTerm: searchTerm,
	onComplete: function(responseData, status) {
		clearTimeout(searchTimeout);
		if(status == "OK") {
			callbackFunction(responseData);
		} else {
			callbackFunction(false);
		}
	}
});

The callback function is the one which will called if geocode was sucessfull OR if the timeout was over.
If the geocode come into onComplete i stop the timeout function and proceed.

I hope this helps you ;)

Exactly what I thought you meant! Thanks for clarifying.

When you have a better solution, don't hesitate to post it here ;-)

I'm having this problem, too.

Is this something we can expect Nokia to fix anytime soon?
