Symbol lookup best practices?

It kind of sounds like you might be exceeding the power budget for onPartialUpdate.  When it gets in this state if you move to the widget/glance loop and back to the watch face, is it normal again for a minute or two?

	//! Handle the partial update event
	//! @param dc Device context
	public function onPartialUpdate(dc as Dc) as Void {
		_partially += 1;
	}

I hope not, I'm not using onPartialUpdate except as a counter so it has at least one line of executable code.

Once it's reset, it's normal for hours. The code that causes the breakage is only executed in onUpdate when isAwake is true:

	//! This method is called when the device exits sleep mode.
	//! Set the isAwake flag to let onUpdate know it should render the second hand.
	public function onExitSleep() as Void {
		_isAwake = true;
		_aWoken = true;
	}

I think it's a bug in the simulator. It happens to me as well once in a while and some other people wrote about it already in the forum as well.

What does mean reinitializes? Same values are reseted at midnight like steps and it's normal behaviour.

I mean that the initialize() function is run again, like the whole watch face code is restarted. I can tell because I see a println in the initialize function in the log file on the watch.

initialise app or view? 

but then what's the difference between the 1st time when you started the app. Those variables also started from 0. Why didn't it crash then? 

class myclass extends WatchUi.WatchFace;

//! Initialize variables for this view
public function initialize() {
WatchFace.initialize();
_screenShape = System.getDeviceSettings().screenShape;
_partialUpdatesAllowed = WatchUi.WatchFace has :onPartialUpdate;
_actInfo = Activity.getActivityInfo();
_hasHR = _actInfo has :currentHeartRate;
_locInfo = Position.getInfo();
_hasPosition = _locInfo has :position;
_sysStats = System.getSystemStats();
_hasSolar = _sysStats has :solarIntensity;
_profile = UserProfile.getProfile();

and more code goes on from here.

I should add that I don't have anything in the AppBase part to see if it is being rerun, but it seems like it might be a good idea?
