Hello all,
I updated an early version of Jogl to the newly JOGL 1.1 june build, but now the app isn't working any more. I get a error in the part where i implemented the TessCallback. So my question is what has chanced in the use/implementation of the TessCallback class.

with regards
Aant

Could you post the stack trace of the exception you're getting? The interface didn't change but there were a couple of bug fixes, in particular I believe in how the combine callback was called.

The error code should be one of
1  
2  
3  
4  
5  
6  
GLU_TESS_MISSING_BEGIN_POLYGON
GLU_TESS_MISSING_END_POLYGON
GLU_TESS_MISSING_BEGIN_CONTOUR
GLU_TESS_MISSING_END_CONTOUR
GLU_TESS_COORD_TOO_LARGE
GLU_TESS_NEED_COMBINE_CALLBACK

Analyzing this code might give you a better idea of what's actually going wrong.

Based on the stack trace the error code must be GLU_TESS_NEED_COMBINE_CALLBACK. You need to specify a combine callback to handle the case where your model has intersecting edges but your tesselator callback doesn't handle the generation of new vertices.
