Yes I saw it too, but I cannot find within the code where the original ids are used. I added an extra id_preserve argument and modified the method to do insert or update without id mapping, but I could not test it so far. Besides, as you already mentioned, the non-trunk version does not support preserving ids and setting id_map parameter doesn't either. Regards --
