So im realy excited to use nuklear and so i tried the demo and got it working in eclipse.
But when i tried to put it in my small engine it created an error in:
                nk_buffer_init_fixed(vbuf, vertices/*, max_vertex_buffer*/);

because vertices is null.
and where vertices is being set is:
  // load draw vertices & elements directly into vertex + element buffer
            ByteBuffer vertices = glMapBuffer(GL_ARRAY_BUFFER, GL_WRITE_ONLY, max_vertex_buffer, null);

so i was wondering if anyone would know a reason why glMapBuffer would return null.
while max_vertex_buffer is 524288.

and other nuklear tutorials would be usefull too
cause the lwjgl demo was realy big and quite conffusing.

thanks any help
