Hello,
I have reinstalled the jmePlatform 3.0 beta and started some examples from the JmeTests package, but I get always the following NullPointer:
SEVERE: Uncaught exception thrown in Thread[AWT-EventQueue-0,6,main]

After a Update to the actual stabel version: the same problem.
Can anybody help me?
It looks like your mouse isn’t being created properly for the canvas… Are you able to run the demos from http://jmonkeyengine.com?
Did you create a new JmeTests project? The old one obviously contains the old code.
Yes, I have creates a new JmeTest Project.
I have tested a bit more: The problem only occurs if the example starts with a “select display settings” frame. The TestCanvas example works without problems.
OS and version? Java JVM and version?
Linux Mint 11 (based on Ubuntu 11.04)
Kernel Linux 2.6.38-8-generic
java version “1.6.0_26”
Java™ SE Runtime Environment (build 1.6.0_26-b03)
Java HotSpot™ 64-Bit Server VM (build 20.1-b02, mixed mode)
Hello,
I still have these problems. But now unfortunately I have one more problem. The jmePlatform crashes during coding with the following segmentation fault:
[java]~/jmonkeyplatform/bin $ ./jmonkeyplatform
Unknown option -Dsun.java2d.noddraw=true
The program ‘<unknown>’ received an X Window System error.
This probably reflects a bug in the program.
The error was ‘BadWindow (invalid Window parameter)’.
(Details: serial 12675 error_code 3 request_code 20 minor_code 0)
(Note to programmers: normally, X errors are reported asynchronously;
that is, you will receive the error a while after causing it.
To debug your program, run it with the --sync command line
option to change this behavior. You can then get a meaningful
backtrace from your debugger if you break on the gdk_x_error() function.)

It looks like a Nvidia driver bug. Has anybody an idea how to solve this?
I have solved my last problem by using the Oracle JDK version 6 instead of OpenJDK.
My first problem related to the NullPointer at the application start can be prevented with the following line:
[java]app.setShowSettings(false);[/java]
I’m still confused a little bit, because a weeks ago all examples works with the settings dialog at the beginning of each example.
Sorry for digging out this, but I came across the same problem today. What helped was deleting the prefs.xml under $HOME/.java/.userPrefs.
Strange enough, this file lived in a folder named _!'o!^@“v!'4!aw"l!(k!)!”&!'4!~w"p!'4!~@!g!$:!.g!w :-?. However, according to this doc the folder name should have a similar name as your game?!
