CLLocationManager is not updating location - ios5

Question

This is related to my other question but I am openning a new one with iOS tags only because it could be that the problem is on native side.
Problem: location manager is not updating location. I tried reading locationManager.location and it always gives me one cached location.
Then I modified the code to use CLLocationManagerDelegate and -(void)locationManager:(CLLocationManager *)manager didUpdateToLocation:(CLLocation *)newLocation fromLocation:(CLLocation *)oldLocation {}
is never being called.
my .h file:
#import "TiModule.h"
#import <CoreLocation/CoreLocation.h>
#import <CoreMotion/CoreMotion.h>
#interface TiMovementModule : TiModule<CLLocationManagerDelegate>
#property (nonatomic, retain) CLLocationManager *locationManager;
#property (nonatomic, readonly) NSDictionary *currentMovement;
- (void)startMovementUpdates:(id)args;
- (void)stopMovementUpdates:(id)args;
#end
.m

Answer 1

You should try putting a breakpoint on this line:
[self.locationManager startUpdatingLocation];
to see if you ever get there as there is no evidence from your code that it ever gets executed.

Answer 2

The answer is that location updating has to be done from the main thread.
In Titanium you just have to call ENSURE_UI_THREAD at the function beginning.
