Resumen
We exhibit an example of a smooth affine threefold A over a field of characteristic 0 for which there exist non-trivial 2-torsion elements in the Euler class group E(A) vanishing in the weak Euler class group E0(A). This gives a positive answer to a question of the first author and Raja Sridharan.
