Ui.requestUpdate() called from onEnterSleep not working

Hi all together,
I'm new here and I hope anybody have an answer of my question.
I created a watchface for Vivoactive 3 and have the problem, that the Ui.requestUpdate() not called, if it run from onEnterSleep and this only on the device native.
On simulator runs without problem. The Ui.requestUpdate at onEnterSleep is neccessary for me to refresh the view with standards after high power mode with modified view.
It seems that's only a problem from Vivoactive 3 (latest firmware is installed).
I found only one Workaround: use onUpdate(dc) instead Ui.requestUpdate. But onUpddate(dc) is not working in on EnterSleep (missing dc).
Use a little trick:

classVAView extendsUi.WatchFace {

varisAwakeMem, isAwake;

functioninitialize() {
WatchFace.initialize();
screenShape = System.getDeviceSettings().screenShape;
isAwake=false;
isAwakeMem = false;
..
}

functiononExitSleep() {
isAwake = true;
isAwakeMem = true;
}

functiononEnterSleep() {
isAwake = false;
}

functiononPartialUpdate( dc ) {
if(isAwake != isAwakeMem) { // coming from onEnterSleep
isAwakeMem = isAwake;
onUpdate(dc);
}
// here regular Code from PartialUpdate
...
}

// Update the view every minute
functiononUpdate(dc) {
...
}

}

My question is now, is this the only one way to use onUpdate at onEnterSleep and is the Ui.requestUpdate problem a known issue on Vivoactive 3?

I'm not sure what you're trying to do in onPartialUpdate here. My guess is you will exceed the power budget for onPartialUpdate in a minute or two, and it won't be called any more until you restart. I would not use this approach.

It's probably that onEnterSleep() isn't being called when you expect, instead of Ui.requestUpdate() not working.

Hi, thanks for fast reply. This code I have test, it works. The onUpdate(dc) in PartialUpdate is run for once only then I set the isAwakeMem = isAwake. So is not the power budget exeeded. The onEnterSleep is definitivly called but not a Ui.requestUpdate in onEnterSleep.

How are you checking to see onEnterSleep is being called on the watch itself? With the sim, you can trigger low power on and off when you want, but it's different on the watch itself, and based on the gesture and time.

Yes you are right, it‘s a little bit tricky. I checked my variables in the called PartialUpdate with if (isAwake) {drawText...}
With this test I have checked all my variables. So I see onExitSleep is called on gesture and after 10 seconds is called onEnterSleep. That all is correct.

Good news, FW 3.30 on Vivoactive 3 solve this problem
