Fancy thing with stream sources.

Hello,
I have been writing some code to show debug AABB for my octree, ok no problem, everything is fine. But now when I try to show the real static data, a lot of triangles of different flickering colors are showed, it is really weird. If do not show the AABB the static mesh is rendered ok. I noticed that when I rendered the static data when showing the AABB's it seemed to be using the AABB vertices instead of the static data vertices, this is why I named the post this way.
Here is the code to show my AABB:
I think it has anything to do with render states because if I only comment the DrawPrimitiveUp call the static mesh is showed ok.
The static mesh use a DrawIndexedPrimitive to render.
Thanks in advance,
HexDump.
Are you calling SetStreamSource() before your static mesh data, after the AABB? Also, SetFVF() as well? If you set a vertex stream and then call DrawPrimitiveUP, that vertex stream will need to be set again before any subsequent DrawPrimitive call.

yes of course this is where I render the mesh ( I took out some params from the fuctions).
Thanks in advance,
HexDump.
