really confused with an error

Newbie & Debugging Questions
#21 
GL15.glDeleteBuffers(vertid);
		GL15.glDeleteBuffers(texid);
		shader.dispose();

is causing the error. is there anyway to check if there is opengl data in the thread?

Yeah, by looking at the source. :emo:

#23

Well the issue is , the object is created , it has a buffer with the vertid and texid so there should be no error.

#24

Yes but that’s not the error. The error is, you’ve got no OpenGL context current in the main thread. Which means either:
a) You created the Display in a different thread to the main thread
or b) You have actually closed the Display
or c) You are actually taking the context away from the current thread in a different thread eg. by creating some other OpenGL drawable.

It’s one of those things; which one? Stick a breakpoint on Display. Just before the exception assert that Display.isCurrent().
