NullPointer at any example (9 posts)

    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?

    Hello,
    I still have these problems. But now unfortunately I have one more problem. The jmePlatform crashes during coding with the following segmentation fault:

    ~/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:

    app.setShowSettings(false);

    I’m still confused a little bit, because a weeks ago all examples works with the settings dialog at the beginning of each example.
