IllegalStateException: No context is current

Hi,

The following sample code works:

Code:

Display.create(); // create context with LWJGL

if (GLContext.getCapabilities().GL_AMD_debug_output)
{
   AMDDebugOutput.glDebugMessageCallbackAMD(new AMDDebugOutputCallback(
   new AMDDebugOutputCallback.Handler()
   {
   public void handleMessage(final int id, final int category, final int severity, final String message)
{
   [...]
   }
   }));
}

In my situation, I am not getting the GL context from Display.create().
The context is created and made active by another native library:

Code:

// The following call calls wglMakeCurrent().
SomeObject.someNativeMethodThatCallsWglMakeCurrent();

GLContext.useContext(someGlobalObject);

/*
At this point I *can* use LWJGL functions like glBindBuffer and so on.
However, AMDDebugOutput.glDebugMessageCallbackAMD() raises the following exception:

java.lang.IllegalStateException: No context is current.
at org.lwjgl.opengl.CallbackUtil.registerContextCallback(CallbackUtil.java:91)
at org.lwjgl.opengl.CallbackUtil.registerContextCallbackAMD(CallbackUtil.java:154)
at org.lwjgl.opengl.AMDDebugOutput.glDebugMessageCallbackAMD(AMDDebugOutput.java:80)

Why ?
*/

Any idea? I'm stuck.

Thanks,
Fred
