Viewport errors in GL3.0

Hi All. I am having a strange issue here. I am writing GL 3.3 based app. There are pretty no examples on programmable pipeline in JOGL (and if there are I will be happy to get refs :)  So I am using my experience from CPP . What I have for now is a simple scene drawing a triangle  .I am using Netbeans 7.1.2 + Win 7 64bit. ,GPU GForce 8600GT GL Version =3.3 .
When I launch the app sometimes it shows up the triangle all right  but in most of the cases it gets a black screen with the following in the output :


Exception in thread "Timer-0" java.lang.RuntimeException: javax.media.opengl.GLException: Thread[AWT-EventQueue-0,6,main] glGetError() returned the following error codes after a call to glViewport(<int> 0x0, <int> 0x0, <int> 0x318, <int> 0x23D): GL_INVALID_OPERATION ( 1282 0x502),

That is strange because I tried even not to call glViewport at all and still I am getting it occasionally .What do I miss here?
Thanks .

I assume you get the below trace by enabling our GL debug pipeline
either by an explicit manual GL pipeline creation or by setting
the Java system property: 'jogl.debug.DebugGL' ?

As you can see in the stack trace, JOGL's GLDrawableHelper calls it
in case a reshape/resize happens, this is intended.

Maybe:

http://www.opengl.org/sdk/docs/man/xhtml/glViewport.xml

"GL_INVALID_OPERATION is generated if glViewport
is executed between the execution of glBegin
and the corresponding execution of glEnd."

But the above is sort of odd, since you explicitly mention GL >= 3.3
and the programmable pipeline. The latter app won't use immediate mode
w/ glBegin/glEnd but VBOs.

Don't know if this helps ..

It doesn't really help to understand what is the problem.For example now I try to setup a renderer where I use a timer for render loops and init a GLCanvas and context in a separate class.So when the overriden reshape() is called ( even if I remove glViewport) I am getting this :
Exception in thread "AWT-EventQueue-0" javax.media.opengl.GLException: Thread[AWT-EventQueue-0,6,main] glGetError() returned the following error codes after a call to glViewport(<int> 0x0, <int> 0x0, <int> 0x318, <int> 0x23D): GL_INVALID_ENUM ( 1280 0x500),

Resurrecting stale thread because it is unanswered and still relevant...

This appears to happen when a gl error occurs in the init() method. Instead of giving a relevant stack trace it ends up becoming obfuscated by JOGL.

As a workaround, I found that invoking my own flavor of init() method from display() on the first invocation of display() does roughly the same thing, minus the stack trace obfuscation.

Hi

Why not giving us a small test case to demonstrate that by intentionally causing an OpenGL error (for example by calling glBegin(), glViewport and glEnd())?
