MapComponent throwing Nullpointer-Exception

[isoc...@gmx.net]

Hey guys

Im having trouble with MapComponent. When running my code on an android-phone it will throw a Nullpointerexception.
Heres the code. Im adding a new MapComponent to a Container labeled GPSMap.

    @Override
    protected void postMain(Form f) {

            map = new MapComponent(new GoogleMapsProvider("xxxxxxx"));            
            findGPSMap().addComponent(map);
    }

- Everything works perfectly in simulator
- On the phone the map will display correctly but in a matter of 0.5 to 2 seconds a NullpointExc. will be thrown.
- MapProvider doesnt matter, i tried with google and openstreetview
- if I insert the MapComponent via Designer the same thing happens



Any suggestions greatly apprechiated

Hi,
use findGPSMap(f) instead of findGPSMap()

Thanks, but it still doesnt work.

The interesting thing is that the map is added and displayed correctly, but the Nullpointerexception
follows very soon after.

And the stack for that null pointer is?

This is what i get from LogCat/DDMS:

[Shai Almog]

Are you using the new async pipeline on Android?

[isoc...@gmx.net]

No.

[isoc...@gmx.net]

Thx Shai, i set the Build-Option for the new pipe now ('android.asyncPaint = true')
and the nullpointer-exc. is gone!

Is this a known issue?

[Shai Almog]

No, I actually assumed it was the reverse that was triggering this. We'll look into this.
