NASA WorldWind not working W10.

[joellapointe1717]

This problem is recurrent for me whatever version of Mapton I tried in the past (multiple years). So this made me prefere other alternatives such as Marble.
Upon opening the .exe file locally, the map engine bar is slushing from left to right than from right to left as if it is loading continuously.
I opened the bottom right notification bubble. Here is the error (Unexpected Exception):

java.lang.NullPointerException: Cannot invoke "gov.nasa.worldwind.layers.Layer.setEnabled(boolean)" because the return value of "gov.nasa.worldwind.layers.LayerList.getLayerByName(String)" is null

This problem isn't unique to my computer. I had multiple different computers in the past.
I also updated Mapton from the updater.

Thanks for reporting @joellapointe1717 ,
Mapton is known to work on Windows 10 too so it should not be related to that, even if I have not been testing it on W10 for a couple of years.

I notice your problems in the past, but my advice at this point is to run mapton with clean setttings and cache, you do that with something like below (with a path of your choice).
mapton64.exe --userdir c:\path\to\nonexisting\dir
Prepend with path to mapton if starting from cmd or create a shortcut with the argument.

Mapton's internal updater only updates data, not the program itself.

[joellapointe1717]

mapton64.exe --userdir c:\path\to\nonexisting\dir

Sorry, It didn't work with cmd. I'm not a programer so my abilities are limited.

It says that mapton.exe isn't recognised as a command or a program...

[joellapointe1717]

I also tried on Opensuse since I distrohop often.
I run the Appimage and this error appeared with the same symptoms:

	at org.mapton.worldwind.WorldWindowPanel.updateScreenLayers(WorldWindowPanel.java:512)
	at org.mapton.worldwind.WorldWindowPanel.initFinalize(WorldWindowPanel.java:251)

	at java.base/java.lang.VirtualThread.run(Unknown Source)```

I'm unable to reproduce here but perhaps the next version will behave better.
I aim for a release this month, if I can find the time for it. I will let you know when it happens!

[trixon]

It's probably a bug in the startup sequence that triggers the error on slower hardware that mine. I'll look into this.

[trixon]

@joellapointe1717 I just tried a possible fix but since I cant reproduce the error I cant test the solution.
Please try the snapshot available at https://drive.proton.me/urls/52THDGYSS0#N50pm9HaI9i9 and let me know the result.

[joellapointe1717]

Did try it (Win and Appimage versions). Same problem:
